Components

A stamped label that starts an action: solid ink for the main one, a pen-line frame or less for the rest.

Related actions joined in one frame, so a toolbar reads as a single control rather than a row of loose buttons.

A mono keycap that names a key or a shortcut.

A stamped button that stays pressed, for one option that is on or off within a toolbar.

A row of stamped toggles: a segmented control for two to four views, or a set of filters that switch on and off.

A month page for choosing a day or a run of days, and the date pickers built from it.

A pen-drawn box that takes a hand tick, for choices that are on or off.

A field that filters a list as you type, for picking species from a checklist too long to scroll.

Label, control, description and error kept together in one readable column, for building forms.

A calm pen-line field for a short value, as wide as the value it holds.

One field frame shared by an input and its units, icons or buttons, for values that need a word or an action beside them.

One box per digit for a short one-time code, such as the sign-in code Fieldbook sends by email.

The name of a control, set in the reading voice beside or above what it names.

The platform's own select in Patina's field, for long lists on phones and forms that must work before scripts load.

A short run of questions answered one card at a time, such as setting up a new expedition.

A set of pen-drawn circles for picking exactly one of a few options; the chosen one takes an inked dot.

A calm field that opens a sheet of options, for choosing one value from a list too long for radios.

A pen-line track with a card-stock thumb, for setting a value or a range by feel within known bounds.

A pill track for a setting that is on or off and takes effect at once.

A calm pen-line field for a few lines of notes that grows with what is written.

A calm sheet that asks for a decision before something that cannot be undone.

A searchable index of everything in the notebook, for jumping to a species, a place or an action by typing.

The actions for one thing, opened where the pointer is with a right-click or a long press.

A sheet pinned over the dimmed page for a task that needs full attention before returning to it.

A sheet pulled up from the bottom of the screen for a quick task on a phone, dismissed by swiping it back down.

A list of actions or view options that opens from a button and closes once one is chosen.

A preview that appears while a link is hovered or focused, so a reader can glance at a record without leaving the page.

A small sheet that opens beside its trigger for a detail or a quick edit, without leaving the page.

A page that slides in from an edge of the window to show a record or a short task beside the page it came from.

Brief slips that confirm what just happened, or offer to undo it, without taking the person away from their work.

A label-maker strip that names a control when it is hovered or focused.

A mono trail from the top of Fieldbook to the current page, with a hand-drawn slash between each step.

Tells every primitive which way the page reads, so menus, sliders and keyboard arrows follow right-to-left text.

A desktop app's row of menus, each holding the commands for one area, moved through with the arrow keys.

A product's main links, with panels that open to show the pages in each section.

Mono page numbers for moving through a long list a page at a time, the current page ringed by hand.

An app's main navigation in a column beside the page, which folds to icons on a desktop and becomes a sheet on a phone.

Mono labels on a dashed rule that switch between views of one record, the active one underlined by hand.

Rows of questions or sections that open one at a time, so a long page of guidance stays scannable.

A wash of colour with a drawn glyph that tells the reader something about the page they are on.

A frame that keeps its proportions as it resizes, holding a print in place until the photo it frames has loaded.

A person's picture in a pen circle, or a monogram print seeded by their name when there is none.

A small stamp that labels an entry's status or kind.

A sheet of card stock that groups one subject: a header, its content and its actions.

A row of cards to leaf through one at a time, such as the prints from a morning's sightings.

Code or data set in mono on a recessed sheet, with line numbers, highlighting and a copy button.

A section that opens and closes in place, for detail a reader asks for rather than reads by default.

What a list shows when it has nothing in it yet: a print, a heading, one line on why, and the one action that helps.

A typeset row for one record in a list, like an index entry: number, title, a one-line hook and its actions.

A pen-line track that fills with hatched ink as a task moves towards done.

Panels side by side or stacked, divided by a pen line you can drag to give one of them more room.

A region that scrolls inside a fixed frame, with a thin pencil scrollbar that stays out of the way of its content.

A dashed rule that divides entries in a list or items in a row.

Toned paper in the shape of content that is still loading.

A hand-drawn arc that turns while something of unknown length is happening.

A ledger for records that compare across columns: mono headings, dashed row rules and typeset figures that line up.

A prose container that typesets plain long-form content, such as a field note or a guide, without a class on every element.

Recharts printed on the page: each series in a drum of the ink set with its own hatch, its strokes drawn by hand through the exact data points.

A file handed over with a message, as a small ticket: what it is, how big, and whether it has arrived.

A slip of paper holding one turn of a conversation, cut from a different stock for each side.

A line in a thread that is not a message: the day, where unread notes begin, or something that happened.

One turn in a conversation: who wrote it and when, what they said, and what can be done with it.

The scrolling column of a conversation: it keeps the latest note in view and offers a way back when you read up.

The steps an assistant took to reach an answer, numbered in order, each one open for its detail.

Theme, paper, inks, accent, variation, patina, density and interface face as settings rows that restyle the whole page.

A list to tick off as you go, with a running tally, such as the checks before a count.

A hand-drawn map of how one thing connects to others, by kind of connection, that turns into a list on phones.

One question branching to its possible answers, each with its reason, with the best fit marked.

Numbers an entry in a run, zero padded in mono so a column of numbers lines up: No. 0012, or No. 0012 of 0200.

Presents one entry as a card to pick from a collection: a cover print, its number and place, a title and a one-line hook.

Lists entries the way a printed index does: a number, a title, its hook on the same line when it fits, and a leader to a reference.

Dates and places a record the way a post office cancels a stamp: a circular mark with wavy lines, struck in ink.

Lifts one line out of an article and sets it large, with a hand-drawn mark and who said it.

A thin strip along the top of the page that shows how far through an article you have read.

A drawn scale with the current reading circled, for judgements such as how sure an identification is.

Adds a numbered aside to an article without breaking the line of reading: in the margin when there is room, after the paragraph when there is not.

Numbered stages of a process, showing which are done, which is under way and what comes next.

Admits someone to a booked event: what, when and where in mono fields, and a perforated stub with the party size and a serial number.
