avoid "ESC" closing?

[Biff]

Is there a way to save (as "Save", not "Save as" or so, e.g. for backing up them) the edits (to a separate cue) in the Chapters Editor without closing it, without confirmation? Or / and to get a confirmation message (before the Chapters Editor is closed)? Or could one remove the key (cannot find it in "Hot keys"), "ESC", somehow to avoid closing without intention? If one accidentally closes the (unsaved) Chaptors Editor the edits are gone / not restorable.

Is there a way to undo edits?

Yes, I will add the confirmation.

Is there a way to undo edits?

Ok, I will implement it too.

Undo will be added in v6 only.

Ah, thank you very much!
