Hi Guys,
Yea we're looking at bootstrap and full responsive. It's a major rewrite, though, but will be worth it.
First step is updating the field library to work independently like plugins, and yes the plan is to use the new TinyMCE for that. We just need to find/make any tinymce plugins we're already using that work with the new version.
I don't have an ETA on a new field library yet but it a high priority for us as it will make a lot of other things possible (like easy config screens for plugin settings or form builders).
Cheers!
