Remembering Scanned Signatures

Is there a technical reason why scanned signatures aren’t remembered when the game client is restarted? Or is it a choice?

I daresay that could cause non-trivial additional server load. It’s nice we have them saved for the current instance, unlike days of yore when they went away when you changed system.

The third party wormhole mapping tools kind of do this. You paste in the signatures and can check shadier that list when you log back in.

But yes, it would be very nice.
