how hard is it to switch to TipTap in Twill v2.x? Also, curious how hard it would be to add custom buttons to TipTap for adding structured content directly in the field editor?

Hi @Olivier if you are not depending on the css classes added by Quill, i think the migration would be pretty seamless, tiptap would load the html fine. And it is definitely easier to customize than Quill. In Twill 3 we made that even easier. In Twill 2 you'd need to override the Vue component.
