The base kit compatibility is quite good (and, by extension, the Alternate Mods kit). The only suggestions I have are:
- Consider replacing R4 \| and R3 #~ with R4 <> and R3 \|.
- Consider adding an F13 key, which has quickly become the new "in" key. You will be asked to make it mod-colored and alpha-colored by different people.
- Consider adding a space bars kit (with an Alice B key).
