es-cards Class Parameter

I would like to request that there be a setting in the admin panel that would allow users the ability to control the number of columns that are displayed on the frontend for all of the es-cards layouts. Ideally each core object that utilizes this class for its output would have (2) controlling parameters:

- Featured Items
- Normal Items

For example, I might want my featured items to stand out a bit more so I might want it to have the normal (2) column es-cards--2 class, but the normal items, I might want to fit more on a page and condense the view so I might want es-cards--4 for a (4) column layout.

Rather than having to make micro adjustments in all of the layouts it would be nice to control this more easily for future compatibility with updates then modifying single lines of code.

- Groups
- Pages
- Events
- Audio
- Photos
- Videos
- Polls
- Achievements
- Points
- Etc..

Thank you,
James
