Thanks for creating this plugin, it's certainly the best rich text widget solution out there. Although, I'm currently experiencing a slight issue where the Bootstrap CSS that the plugin loads collides with the CSS of the WordPress editor preventing things from correctly showing.
This includes any object that has the class of "hidden" as Bootstrap includes css for .hidden. I'm fairly sure that there are also some other minor ones that I have not yet disovered.
The worst part is that this blocks access to any screen options as they are hidden, and to use them you need to remove the .hidden class using the inspector or firebug.
Could you please fix theese CSS issues as soon as possible? Maybe only load the CSS at the widget screen, and remove any unneccesary classes?
Being a plugin developer myself I appreciate you creating this widget, but please fix this problem asap :)
Thanks in advance,
