Idea Summary
The icon picker modal dialog in page designer is quite small, and is even more noticeable in 2k or even 4k screens. When you know the name of the icon is just ok, but when you are just looking for the best icon for your needs, you have to scroll a lot even having space enough in your screen to fit much more icons. It would be nice if this modal could be resizeable / bigger / responsive.

Use Case  

Preferred Solution (Optional)
Make the icon picker bigger, or responsive / resizeable showing more icon columns.
