Apps UI - Make more compact

[nj]

After around a year of using Cloudron, I have installed many apps, and now the admin interface needs scrolling. I have a really wide screen but the layout won't adjust to fill the available space (4 cols only).

If only there was a way to fit more items on the screen it would be easier. For now, supporting upto 6 or 8 rows would do.

PS: The design of the App Store would do too.
