[Feature Request] Extensions grid

[BaccanoMob]

Having single lined list of extensions is just wasting a ton of space in the middle of the screen (might be difficult to point of which install button to click for larger screens).

Instead having them as tiles (similar to the library) can save space will be quite compact.

if this is possible then also a setting to set number of extensions per row (might help adjust for different screen sizes to users' needs).
