EVE Launcher

I'm an avid expedition runner. As such, I'm frequently bouncing all over the region chasing the escalations. I like to scan signatures in between each escalation system, and see if I can find any other combat sites to grab even more expeditions. The problem comes in that often I can't remember if I already scanned the signatures in a system or not, because ignored signatures just pop back into your probe scanner when you re-enter a system. Would it be possible to make a change where ignored signatures stay permanently ignored? They would stay ignored until either despawning, or the player manually puts that signature back into the scanner window.

It may seem like a small issue in the grand scheme of things, but believe me it does become a problem over time. Anyone who actively runs combat sites knows what I'm talking about.
