I sometimes run into problems where the two Find Results windows are not enough. It would be helpful to have more than two Find Results windows available at the same time.
I would be OK for some way to clone the existing results from window 1 or 2 to some new window with the same manipulation ability and same click ability as the current Find Results windows.
You can clone the Find References Results window multiple times if you want, so that you can keep and compare several different sets of results. Not quite the same as the IDE find results window, but hopefully this will help.
