Thanks for the info! Sadly, it means that I have to change the way I work, or I need to stay on 1.9.30, because I often have dozens upon dozens of tags to add. Not being able to drag and drop is a major hurdle for my workflow in general, but using an external html editor will also be a bit of a time loss (albeit lesser than going back and forth constantly to copy and past start and end tags).
I mostly review and enrich files post conversion.
While I understand Sigil was never meant to be a full-blown html editor, it was still agile and versatile enough that I could do everything I needed to do within the same software, and that meant saving a lot of time in general, because I don't have to go back and forth between editors to do x specialized thing, then back in Sigil for x other more specialized thing, then another software for x and y, and back to Sigil...
Please know that I'm not telling you all that because I'm angry, but just so you understand the needs and maybe (maybe!) re-enable it in the future once it become safe to do again.
