#3 mouse icon switched to left‐handed

[Tokushima]

I would like to see current button mode if it's for left-handed or right-handed quickly without seeing the task tray.
I don't want to take my eyes off my typing/editing area.
I hope that
1) you can specify/register a mouse icon for left-handed mode. and
2) you can specify/register a mouse icon for right-handed mode. and
3) mouse icon shall be switched automatically by button mode.
4) you can see current button mode without seeing the task tray.

I'm OK if it's simple system like changing color of mouse icon.
