Allow Resizing Of Control/Cursor/Etc Keys Bar or Space Out Keys More, Long Hold Cursor Keys

On some devices, the tab, control, escape, copy/paste, and cursor keys are hard to press due to being small, too close togther and close to regular keyboard keys. Being able to resize the bar or otherwise making the keys larger or more spaced out in general would be nice.

Also, being able to long hold the cursor keys like iSH, as opposed to having to repeatedly tap the buttons or use ctrl-a/ctrl-e would be useful.
