I dont think input display will help much, it's much easier and practical to write things like delays, timing on the notation. Or explaining specific stuff like "Valk's [w]j.B j.B land 5D 5B is only possible if you're below your opponent", or "In order to connnect [w]j.B j.A after a 236C 9D, be aligned with your opponent then [w]j.B"
Not sure if you guys are doing it now, but I had a hard time learning Valk's timings and combos and stuff like this would certainly help.
