I didn’t realize that removing characters in a note title does not stop at first character of it, but then removes the note and joins the remaining text of its title with the note above. Undoing this action didn’t work.
You can try with creating three notes in outline view. Putting the cursor in the middle of the note title of the last one and then deleting characters using backspace until the note is deleted. Now press enter and accept the change and then try to undo the deletion of the note. I don’t get the undo to work.
I create three (or more) Notes in Outline view then place the cursor in the Name of the last Note and press backspace until the name disappears. When I hit enter the Note itself is deleted, which seems reasonable. However using cmd-z to undo the last action first of all produces a Note with no name and cmd-z again results in that Note having the name I gave it before deleting the name and deleting the Note. Am I misunderstanding the issue you are having?
I’ve reported this to tech support. There are two separate issue at play here: the title editing and undo.
Editing title
The issue with backspace delete appears to apply only to Outline view and then only when editing the title in the view pane as opposed to the title a the top of the text pane (I tested both). The effect does not apply to forward delete, only back-delete (the Mac norm for delete).
I suspect the effect described is an unintended side-effect of v10.0.0 changes to editing outline titles. These changes were specifically requested by users, but the back-delete running past the ‘edge’ pf the title is likely not intentional.
Undo
Undo is working but perhaps not quite in the manner intuited by the original reporter. Undo has no effect whilst in ‘edit in place’ mode, i.e. editing the title in the view pane. Once leaving the edit mode, Undo will roll back to the state before the edit started.
If people want a different behaviour of undo in this context please write directly to Tech Support (tinderbox@eastgate.com), as any change to this undo behaviour would require a change to the app.
No further reporting of these issue is needed as here developer is now aware (I’ve emailed them directly).
This was a feature requested in the forum, which had some vocal background. As I recall, the proposer thought Tinderbox was a bit ridiculous in not supporting this. And deleting text beyond the start of the note is a fairly unusual thing to do.
My impression is that this feature has not proven itself to be well loved.
