I really thought a request like this already existed, but a quick search didn’t reveal it. I would too like to be able to customize buttons & sliders on the hud screen. As mentioned by @Jackalus_Mills, the rudder slider can be used as a break as well. Read on this here.
My problem is that the power slider sits too low. When doing patterns I would like the slider to be higher, to give more comfort when controlling low power.
If I can’t find a duplicate of this (will search some more), you’ll have my vote.
P.S. don’t forget to vote for the feature request yourself!
EDIT: found this:
None did get any votes…
I believe your request is different as it suggests you ask for the ability to totally customize the hud.
