I think that being able to change your interface while playing is a great idea.
Mayby when you are playing soldat you can push 'esc' and click change interface and pick your interface.
MM will probably have to code something, but to me it sounds like a nice feture to have.

Theres no harm to the suggestion, but it seems a bit inconsequencial. Pointless :/

Yea i sense a glitch. Changing things in game seems to have been having some lag lately
