The editor now has undo and redo. Markleaf saves as you write, so a mistake was saved too — select everything, press a key, and the note was gone. There are now undo and redo buttons in the row above the keyboard, plus Ctrl+Z and Ctrl+Shift+Z on a hardware keyboard. Typing over a selection, a replace-all, or deleting the lot is a single undo step. The history covers the note you have open.
