Nigol, can you look at possibly fixing the behaviour of the "TOC Editor" screen's "Apply" or "Save" button when the "Add" screen is open.
I was in the middle of editing one of my huge .epubs, at the Add screen, and wanted to save my work-in-progress thus far. I clicked the Save button and the Add screen was closed. After opening the Add screen again (it took a loooong time on that .epub
), I tried to click just the Apply button and the same thing happened. Instant closure of the Add screen.
Can you just leave that Add screen "as is" and wait for the user to Close that screen and then click Close to exit the TOC Editor screen to finish. This will allow multiple saves while the editing task is still in progress!
