Comment #3 on issue 432 by tu...@tudorgirba.com: Popup should appear only when a certain modifier key is pressed http://code.google.com/p/moose-technology/issues/detail?id=432
What we want is to prevent the popup to block the main process. The problem is that when I look at the system complexity for example, it is very easy to simply hover over the wrong class and then I have to wait until the rendering of the blueprint is complete.
So, my suggestion is to actually only trigger the popup when a modifier is pressed (Shift would be my choice). If the modifier key is not pressed, then hovering would not trigger the popup.
