Improved DIV creation in the Guide article editor

I just noticed a keyboard shortcut to create DIVs in our articles exists.

It's nice to have, and I have a few suggestions:

• Add a visual cue in the editor to show that the content getting created or selected is now in a DIV.
  • You could create an outline around the DIVed content.
• Add a way to quickly add a class when you create a DIV; otherwise, just creating DIVs in the editor or with a keyboard shortcut still requires navigating to the code editor to add it, making that feature slightly meaningless.
  • It could be added to the toolbar at the top with a dropdown with options like you have with Tables.
  • Add an option to save and reuse classes. This would be extremely useful for creating custom things like Tip, Note, and Caution boxes.

Thanks for your consideration :)
