I haven’t actually worked with this setup yet (set it up a minute ago), but I don’t see the downsides.
I shifted all of the view functions over by 4 and they take up the rest of the function keys. Redo is now shift + F4. I might end up switching Undo and Redo (to “childproof” Undo) but I can’t tell which would be a worse misclick. Guess we’ll find out? Anybody else want to partake in this idiocy?
