What would be really useful with the distance guide is if you could force an object to be centralised between walls. For example, when you are placing a bed within a room, the distance guide gives a distance from each adjacent wall. Maybe there could be a check box saying center?
If the distance to adjacent wall edge would not disappear when the cursor is above wall line, this could be achieved by entering "2/" to the tracker. This would also enable other division options.
