Yamaha is slowly moving back to the $20,000 home organ market of the 70's LOL!
While those suggestions have some merit I doubt if there are enough other users with the same requests. Most don't delve that deep. A software update is a possibility but a new hardware design with the limited sales of a 6k instrument doesn't seem likely.
Work with what you have and maybe you'll get more comfortable as you learn. Good Luck.
