I would like to be able to r-click on these icons to be given the option to mass deleted all specialized research facilities for that area of research. This would be used when you have researched everything in that tec branch and no longer need the specialized facilities.
A definitely excellent idea. I have played the game once so far (and still going--it's a big campaign). I have wished for this feature non-stop now that I'm almost finished with all research and I have about 75+ colonies to sift through.
