One thing I'd like to ask about is the typography.
I think aesthetically it would look better if the legends were locked across the board rather than what appears to be a capitalization from the font.
Backspace instead of BACKSPACE, Ctrl instead of CTRL, etc. I think it would look a lot cleaner to opt for CTRL, WIN, ALT, etc. Similar to the likes of Penumbra and the others.
For kits, I'd be interested in adding to the special modifiers with different arrow keys perhaps. Symbols/Directions over written text. Similar to Hyper Fuse and Granite.
Either way, definitely buying this set, just throwing out general ideas from current sets that were successful to help the #HYPE.
