You wrote a follow-up checklist on Tuesday. On Friday the patient mentions their sleep is better, and you want to tick that line, not open an editor, retype anything and save.
Editing where it sits
On a patient's notes, use the pencil button on a note, or double-click its text. The note turns into the same editor you wrote it in, in place. Click away and it saves. A Save button is there as well if you would rather be sure. Clearing the box or changing nothing saves nothing. The note then shows an edited time next to when it was written.
A note over 240 characters is shortened in the list, with Show more under it. Editing and ticking work on the whole note either way.
Ticking a checklist
A line written as a checklist item (a dash or asterisk, then a box) shows a clickable box in the saved note. One click saves the change, the same way an edit would, and shows in the edited time. Only the box itself changes: the rest of the line, including its indentation, is left as written. The slash menu inserts a checklist for you.
The note updates on screen at once. If the save fails, the change is reverted and a Couldn't save message appears above the list.
