Blender 2.8 select with left + drawing tablet

I’ve changed to select with left mouse button which corresponds to the pens tip but doing this messes up selection too much since Blender just seems to switch RMB with LMB. It’s not really usable with a drawing tablet since a lot of selection is already done with the LMB which then becomes RMB. Like in the dopesheet timeline, selection becomes RMB but I’d like to select that with LMB too. I’ve tried changing Select Keyframes to LMB but that didn’t work. The left/right Mouse button change needs more detail and options. I also think Blender should get much better Tablet support.

I have a custom setup that works well with drawing tablets and is fully Left click select.
