Thank you for your reply I appreciate it. I am aware of the editing keyboards but have always found them horrendous. I do know the keyboard commands, but I am constantly needing to learn new software, so the key commands are different, which makes editing keyboards very limited.
Additionally, I enjoy learning new languages so having a keyboard that would change with the language that I am learning would be really helpful. Especially with languages like Korean, Japanese, and Chinese.
I also think that although Art Lebedev didn't sell well, it was due to its insane price and terrible software, so there would need to be a more moderately priced option (at lease in my opinion) for it to be deemed niche. There are plenty of people in the same boat as me, and I know that it could be useful.
