Give mods a permanent Icon so we know what they started as.

I think it would be useful to have an icon that indicates what the Mod started out as(Grey, Green, Blue, Purple, Gold) Now that I have so many Gold Mods from levelling up it's a pain to check every 5 dot Gold Mod to see if Secondary Stats boosted X4. If I could get an indicator of all my Mods that began as Premium Gold or Purple and sort them like that it would be much easier.
