Is it possible to get special characters such as single-quote and double-quote assigned to the alpha characters? So they appear in the long-press character lists instead of (or in addition to) having to press "Sym"?
I'd add the single-quote to the "q" key, and double-quote to the existing list of "upper case" characters on the "D" key in my UK keyboard layout.
Also on my list would be a semicolon on the "S" key and a colon on the "C" key.
Such an enhancement would significantly increase my typing speed.
