I really do like people making suggestions as most of the recent good changes have been suggestions from others!
But I really dislike having to argue with people who think only they know better and that they can control what direction Sigil goes. Especially when there are valid reasons for things working the way they do and have done for a decade.
So please stop.
Given Sigil is opensource, you can always tweak it to work the way you want and I am okay with that. Just do not call it Sigil.
FWIW:
BeckyEbook has many changes and tweaks she makes in her own Sigil builds. So it is achievable.
