Please hold off on icon requests at the moment. The theme currently contains 240+ icons but I'll be constantly updating to get back to the 600s. Once I'm there you can start emailing in your requests.
Recommended icon sizes:
Go Launcher: Default Size (small)
Apex Launcher: 100% or 105%
Nova Launcher (Prime): 100% or 105%
This is NOT a standalone app, you need a launcher such as Go, Apex, Nova, etc that allow custom themes.
Installation:
Install Go Launcher, Apex, or Nova (all free in the Play Store)
Install this theme
Find Minimal UI in any of the launcher's theme settings, then apply.
