Drop shadow on app icons

[GeopJr]

App stores add shadows and/or outlines on app icons to distinguish them from the background and give them some depth.

Would there be interest in doing the same on the apps page? (I can PR it if needed)

No shadow	sm	default	md	lg	xl	2xl

I'd say default (tailwind drop-shadow) or -sm look the best IMO

I'm happy to review something along these lines, I think those two options look pretty good.
