Although having the game tell you that a particular Rank 5 arcane is equipped is superbly helpful, there are still some situations where I would craft R5 arcanes and proceed to sell them but selecting different ones would still alert me that is it attached to a Warframe. I would like to suggest a "favorite" system, similar to the ones we have in Loadouts. Only this time, we would mark or favorite the arcane we have equipped and shared across multiple frames so that we do not accidentally sell the equipped ones. This in turn prevents requipping arcanes that we not supposed to be unequipped.
