This layout makes heavy use of TMK/QMKs Tap/Layer-Modifier feature, It's incredibly useful and never want to go back to a board that doesn't have it. Might get rid of it altogether, or like I said I might make it a One-Shot-Modifier for F# keys. Layer 5 is currently just an experimental layer and I don't typically use it on a regular basis. My other idea was to make Tab a tap/hold function layer with the F keys on the left side of the board, just like the numbers are on my left-spacebar function layer. Problem with this is the travel distance between FN5 and the left side of the board for left-hand usage. One would be to use FN5 as a One-Shot-Layer key for the F number keys. I've been trying to think of a way to implement that as a feature and I've got two different ideas banging around in my head. The downside to this is that I don't have access to the F keys with only my left hand. I stole this particular idea from the KBP v60 layers, since those were the first boards I used that had them and I absolutely fell in love with the setup. One for left hand and one for the right hand. I also really love having dual arrow keys.

It had to have an integrated number pad in it, which is something that I've been using forever in my 60% boards, but I also wanted the ability to type numbers and special characters with just my left hand, which is why my Left Spacebar gives access to the numbers and arithmetic symbols on the left hand side. I had several goals that I wanted to achieve with my layout.
