Success!
ePub3-itizer plugin and cssRemoveUnusedSelectors plugin worked fine with new build.
I also downloaded this
ReadiumReader plugin and it worked fine as far as I can tell. (I don't usually use this plugin.)
Also, one thing I noticed is a missing image(?) in some of the pop-up windows. See attached screenshot of window when closing an epub that has been modified. It doesn't happen all the time, though, and I'm having difficulty reproducing it consistently.
This is what I did:
- open epub, make a change in text, close epub — pop-up window asks if you want to save and Save button is present
- choose Cancel
- run ShowSemantics plugin — Close button is blank — click it anyway to close window (this blank button is not new; it was also blank when running Sigil 1.9.30 but I didn't bother to mention it, perhaps I should have)
- close epub — Save button is blank sometimes, other times it's present
ETA: Okay, this is interesting. When I get a blank button, if I click out of Sigil (e.g., click on my Desktop) then click back into Sigil the blank button is fixed, i.e., blank button turns into the Save button. This happens with the ShowSemantics window as well — clicking my Desktop then clicking back into Sigil fixes the blank button.
