I was going to suggest a separate suggestion, but this one is close enough to add my feedback here.
I would like to add one detail though:
Your icon packs are nice, but will you please add the functionality to use external icon packs?
I would absolutely love to be able to change both the default folder icon AND folder-specific individual icons from an external icon pack (like the incredible ADW BuuF GuuF Folders pack (https://play.google.com/store/apps/details?id=org.fractalsystems.iconthemefolders)

And while we're at it, it could be Nicole change the folder solid color separately than the bar one on the theme settings.

Thank you for listening!
