At least on my M1...
I can switch the role of the wheel by pressing wheel-right (BGMT_PRESS_RIGHT), say I can control Shutter speed or Aperture, on Canon the box around the current selected variable has bright green corners, on ML it looks like this:

Which one is selected?
Can the mode be detected by ML and the correct text highlighted ( eg. different color ) ?
Thanks
/PS: I had to upload my own ML picture mode screenshot since I could not find any recent one on Google, but there were some in movie mode.
