Option to disable layout changes in docker view (imaging)

The docker layout function to customize the Imaging screen is really a great feature. When working with my notebook out in the field and the buidin mouse-pad, it sometimes happends, that I accidentially move, disable or close one of the items.

Would it be possible to add a “lock layout” switch to disable layout changes?

I wen’t through Issue ~~#902~~ already but would still highly welcome such a feature.
