Since I have been working on a filter with a lot of components there is one feature that I think no one has touched on but would be cool to have ,at least for me. Is have a Lock Component where once you position a component and its subtree in the edit workspace you can lock it so it will not move from that position until you unlock it.
Sometimes I try to go to fast in scrolling and grab another component and move it. It really stinks if I have move subtree checked then it ends up moving the whole thing then I have to go back and reposition everything.

Stupid things happen to computers for stupid reasons at stupid times!
