When using actions "Decrease/Increase playrate by one semitone" several times (2* decrease, then 2*increase), the playrate knob remains highlighted although the numerical value shown is 1.0
And also using "Transport: Increase playrate by ~0.6% (10 cents)" action will not highlight the changed state of the knob, while the opposite action ("Transport: Decrease playrate by ~0.6% (10 cents)") will do highlight the knob for such slight change.
Inconsistency here.
