Qwerty for letters and mods.
Qwertymods layer switches some Modifiers around
Numsym puts the number keys across the top row like a Planck. Arrows are on hjkl which makes the other NumSym dynamic from my other boards fall apart
Function layer replaces the top row numbers with Fkeys.
Numpad layer makes a number pad in the center.
Fkeynumpad replaces the numpad numbers with Fkeys.
Adjust layer has macros and configuration.
