Arcanes should have the "in use" overlay or should be locked from trading

[DarkRuler2500]

Over the past few days I have decided to sell lots of my old Arcane Enhancements but i came upon one issue: It is not clear which arcanes are in use and which are "floating" in my inventory. I have wrecked so many loadouts by selling the arcanes because i sold those that were installed in my loadouts.

Perhaps a setting in either the Arcane menu or an overlay in the trading menu would help alot here. Because with so many different frames it is always bothersome, that I had to reinstall them all the time.
