Hello,
I like the code snippet manager a lot, but I find a little uneasy, that it does not switch back to the editor window after I insert (apply) a snippet into the source. I don't know what was the plan, but maybe this is a bug, because I saw the snippet window gets the focus on mouse hover. The other windows (like the TODO) do not get the focus on hover. Maybe it tries to switch back after I press the apply, but since the mouse pointer is still in it's window, it still gets the focus, so the editor can not get back the focus. I have not checked the CB's source, this is just my theory ;-)
