To-dos get a priority, and a bolder set of checkboxes.
Priority. Add one to three bangs right after the tag — /TODO!, /TODO!!, /TODO!!! — and the empty box's border takes the colour of the level: green for a plain to-do, then yellow, orange and red. The bangs stay behind the box, and ⌘⏎ or a click keeps them when the state changes. /TODO !! with a space is just a to-do whose text starts with !!. Filled boxes are unchanged: their fill already says the state.
Checkboxes. Play, pause and the hourglass are now solid; check, x, asterisk and minus are heavier to match. The play triangle also sits where Lucide draws it — it was 3% too large and a touch to the right.
