I recommend getting it from GitHub which I update more frequently:
https://github.com/ArmoredColony/ARMORED-Toolkit
This addon holds my personal collection of Blender modeling scripts, matcaps, hotkeys, UI theme, etc.
You can selectively enable or disable the things you want. For example: you can enable Maya style Navigation but have my extra matcaps disabled. Maybe you're only interested in my Blender theme and nothing else; you get to choose.
