summernote-cleaner v1.0.9

A plugin for the Summernote WYSIWYG editor.

summernote-cleaner removes the unnecessary and possibly layout breaking Crud that gets added by MSWord, Open Office, and Libre Office Documents.

The plugin can function in a couple of different ways. It can have a Toolbar Button which allows the Cleaning of the Editor's Text, or Pasted Text can be Cleaned when Pasted into the Text Editor.

The plugin can also limit the number of characters, with options to display text and/or HTML count in the status bar area.
