Revising C9 Heading Block with H Buttons in dropdown

[covertnine]

Can we revise the c9 heading block settings for the H attribute to be in a dropdown vs. below it in a row that spans 2 rows? It'd make it easier from a ui/ux perspective by not blocking the heading below it.

Couple other ideas a little related to this would be adding a few font style buttons:

• All caps or uppercase (built-in CSS class for bootstrap)
• Capitals
• lowercase

Another enhancement for this block would be to make it so if you hit 'enter' it saves the block and goes to the next paragraph like the default heading block does. Currently, hitting enter just goes to a new line.

Desired functionality is to hold shift + enter to go to new line vs. just enter. That way you can quickly type out the heading and hit enter and go back to paragraphs.

Do-able?
