Here's another thing I noticed while using GSA.
Sometimes when I'm using private or semi-private proxies they stop working temporarily. But GSA then tests them, and when I open up the proxies tab I see proxies on red that say "successfully tested on ___".
Could there be some checkbox (or automatic feature) that says like this: automatically enable tested and working proxies (or something like this).
Again, this would save time and prevent disasters, when at least the working private proxies would be automatically chosen.
Great software though. Not complaining
