- <input type="number" min max step>: typed digits replace its value (a minus when min allows one, a point when step has a fraction), Enter or leaving the field commits them held between min and max, the left and right arrows step it. - <input type="key">: Enter or a click starts it listening and the next key is its value, Tab, the arrows and Enter included; Esc stops it listening, Backspace clears it, `shown` names the value, and ui_capturing() tells the host to leave its keys alone (through the frame that ended it). - note="..." under any control's label (.ui-labels > .ui-label + .ui-note); a range's (or number's) value with decimals, format="percent" and a unit. - A popover with `anchor="id"` (the nearest element of that id) or a bare `anchor` (the element before it) sits beside it by `placement` (right, left, bottom, top), its margin the gap, opens to the other side where it would leave the screen, and is kept on it. - A tooltip's title splits into lines at a newline or a written \n. - text-shadow, inherited, drawn sharp under the text. - ui_opacity(): the group opacity a native's draw is at. - border-image is drawn as painted with no background colour, tinted by one, and not at all when that colour is transparent (it drew a white nine-slice). - A picture file is drawn untinted, as a browser draws one; an atlas cell (prefix:name) still takes the color around it, and an <img> with its own color is tinted by it. - The render3d backend loads a picture again when its file changes or appears (a failed load was kept for ever), and at once after ui_image_reload(path); takes a path with a drive letter (C:/...) as a path rather than an atlas; and slices a nine-slice by its texture's own width and height. - ui_inputs.ludic and ui_look.ludic; LANGUAGE.md and the changeset say all of it.
