No comments on the keys. I'm pumped to buy way too many of these key packs.
I do have a layout recommendation. When you have a set of keys that comes in both text and icons (for example, text/icon mods), the icon keys should be in the same place as the text keys just for consistency.
For example, the icons in the "icon mods" pack bottom row should have the icons match the text pack of "Ctrl, super, alt, alt, etc...". This will make it easier for people like me to know what key each icon corresponds to.
