I share my production room with several people. It's inevitable that someone will un-dock panels or remove them. I can't tell you how many times I've had to rebuild my workspace. The "Revert to Saved Workspace" is a good feature, but if a "Lock / Unlock Panels" checkbox was available, I could make sure it never happens. It is way too easy to un-dock panels even for me. When I put a rookie in there they destroy the workspace every time.
