Locking of Magic Sheet Icons#425

would be great to lock the background image or to have a category Background, which you can’t move, while moving the fixtures. we use in our theatre a lot of the magic view, for every show we save all positions in background image where I insert a grid. we use this as a digital Plan

As of the upcomming update there will be a built-in grid in the MagicSheet (which you can turn on/off) with supported snapping. Would that cover this issue?
