In my mind this is on the radar and as such I have not mentioned it - Mitch’s post made me reconsider.
I have my layer and properties tabs docked on the right side of the screen. Properties on top and layers below.
I have the following keyboard shortcuts:
F3: '-_Properties _Visible _Toggle _Enter F4: '-_Layer _Visible _Toggle _EnterI cannot reproduce this consistently but every now and then (but way too often), when using these shortcuts to toggle the tabs on and off, one of the tabs will be parked next to the other instead of on top of each other.
