Toast

A customizable and responsive toast notification system...

Tube noise over anything. A static filter by default, or a capped canvas loop that pauses off screen.

One cell per character, with a drawn caret in the active one.

A key with two pixels of implied depth under it. Pass `glyph` for `⌘`, `⇧` and `↵`.

A status lamp and the line it sits in. Four tones, and the idle one holds still.

Page numbers as joined cells, so a run of them reads as one control.

Three pixels of track and a light in it. Pass `indeterminate` for a segment that sweeps and leaves.

Terminal-style radio marks in their unchecked and checked states: `( )` and `(•)`.

Two flashes and a rest, the way a warning lamp blinks. Pointing at it stops the flashing.
