I think we need to be able to modify circuit from a circuit schedule. There could be a drop down to select circuit numbers and panels instead of having to do it from the plan view every time.
Also, pick new host with objects that are heavily circuited. Pick new is greyed out if there is a lot of circuits on an object which keeps you from moving objects to knew hosts, this is Autodesk's answer to performance issues they were having when doing this. I rather have it take a long time to move objects, then having to uncircuit all of my devices just to move a panel.
