Hello Vlad. This thread started 1.5 years ago with a Framework employee writing about the design of the Framework keyboard, and since then it’s been mainly Framework customers (or fans) discussing what they like or don’t like in keyboards.
As far as I know, this is not an official support channel, so Framework may not necessarily respond.
You may get more of a response from Framework in the “Framework Support” forum, where there is already a topic requesting keyboard layouts: What keyboard options will be available? - #69 by joe_skinner .
Finally, you can always buy a blank keyboard an a label printer, and make a custom keyboard with any labels you want on it.
