I'm just getting used to the new symbols menu and for some reason the grid view is harder to see which is which at a glance especially when those box icons look identical. I'd suggest making the icon smaller and making the title of the symbol larger and above the icon with the instance number below. That way you notice the title first. Additionally it would be awesome to control the icon but i know that would be a big process. But the first idea i think will make it more intuitive.
Great work guys on the new features!!
