The changes to thermal imaging are largely enough of a step backward for most people that it seems necessary to revert it back to 208 TI.
The new adjustable contrast rather than just the auto adjustment is welcome, though. Allowing key assignments for this manual adjust mode on/off and up and down would be helpful.
Perhaps either up or down key assignments trigger out of auto contrast mode, and both of them at the same time go back to auto mode.
Further improvements to the TI are desired, but it appears this was not quite the right path to be taking on some of the changes.
