Hello.
I'm using the index editor a lot, and I noticed that the entries are not saved in the EPUB file. That is, if I add some entries to the editor (even without creating the index afterwards), sigil saves the list somewhere. So if then I open another epub file and then the editor again, I get the same entries.
However, if I launch sigil from another user on the same PC the editor is blank.
So the question, as per the title, is: where does sigil keep this list? It might be useful to pass it from one computer to another.
Thanks
