Hi guys,
Just to add to your list here:
http://forum.wpbeaverbuilder.com/knowledge-base/known-incompatibilities/
It doesn’t work nicely with wpDataTables - http://wpdatatables.com/ tinyMCE buttons
and WP Edit Pro custom tinyMCE - https://wpeditpro.com/
I have also noticed some strange behavior when utilizing specialized widgets from https://www.dev4press.com/
Best regards,
Michael
