Will sigil ever be compatible with the M1 processor?? I've tried multiple times this year (Nov 12, 2021 today) and it never works. Have a 2020 MacBook Air.

Just a note: This hasn't been a WYSIWYG editor in a while. The dev removed that portion of the app and split it off into a separate app called PageEdit (also open source).

I have used this app only once when Amazon was refusing my book in Calibre's mobi format and it saved my life. :-) I opened with Sigil the epub generated by Calibre and generated the TOC (Tools/Toc/Generate at that time) then I opened the edited epub in Kindle Previewer or kindlegen and converted to mobi. So 5 stars for this invaluable tool!
