When in FBT mode there are options to move/rotate your trackers under advanced options.

After the trackers turn off / disconnect all FBT related options disappear, including the tracker move/rotate adjustment buttons..

Retaining the ability to make adjustments after freezing on disconnect would be very handy, especially if laying down or wanting to get comfy under blankets.

Sometimes thingsend up a bit pretzel, or you start laying another way and want to rotate your chest to align better.
