Close from commit: 1dde0e331e9aee31a344575c2f95f1e551d888f4 by Claes Nästén
In what way would you like these panels to be fixed at their position? I personally like the fact it is possible to move then if wanted.
I assume the "solution" to this would be to add an auto-property in the style of Focusable but Movable and add it to the typerule section for panels, would that work out for you?
