Enhancement: Improvements to RMP card view.

[MattRWallace]

The way classes are formatted in a table, the RMP card (compact or standard) does not display well. The clean view in the README screenshot required deselecting several rows and resizing the column. We would like to improve that experience for the end user.

Ideas:

• Change column with from the extension.
• Add an option that would tell the extension to display the card in a newly inserted table row below the class row.
