I think it would be better if filtering in the selection sets had the option to only filter controls and not Sets. As it is, if I want to add arm controls to a set, I filter "arm" and great, my arm controls show up. But now my selection sets disappear since "arm" isn't in the name of the set. So I have select what I want, delete "arm" from the filter, and then right click Add to set. It would be easier if I could check a box "only filter controls" then I could quickly filter, add, filter, add etc.

Thank you for the suggestion! We've been taking a look at the filter for the next release so I'll make a note of this as something to look into as well.
