Thanks for creating such a useful plugin.
I have one suggestion concerning the Titles.
When I created the Widget Block and then added the Widget in Appearance > Widgets, I expected that the title I used in the Widget Block would be automatically used as the Widget Title. This is not so, and I so I changed the default "Just another WYSIWYG Widget" widget title to match my Widget Block title.
Is it possible to have an option on the plugin to automatically set the Widget title to the Widget Block title?
As a developer it's no big deal for me to set it in both places, but a non-techy editor might be confused when they change the Widget Block title and that change is not reflected on the site.
Also, since we'll be using this tool for client sites it would be nice to have a way to remove the "donate" notices. Maybe you could provide an authorization code once a donation has been made that can be entered and verified to remove the notices.
