I believe we are talking about the labels on the keycaps here, for the most part. French, Hungarian, and non-Latin input is something doable (since the keyboard is fully programmable), but I’m not sure that the Dvorak caps should reflect that, too. We’d end up with endless variation then.
Something that works for most would be best. Both @kaia’s and my first proposal was aiming at being something like traditional Dvorak, with mods and some special keys in the same position as on the Model 01’s QWERTY layout. The colored layout I posted earlier deviates from that a lot, and it may not have been the best idea to post it - apologies!
As an example, the Kinesis Advantage has dual QWERTY/Dvorak legends, and they kept a lot of the special keys the same between the two:
This is a good goal to keep in mind, I suppose.
