Frankly I disagree with this suggestion.
A FAR better option IMO would be to allow us to Remove mods from a character while in the Mods Inventory/Manager instead of having to go INTO the character to remove it.
OR
Just allow us to jump into the Character Screen from the Mods manager where we can unequip it w/o having to go search characters.
Though honestly that seems like it would be harder than just adding a REMOVE button.
Nothing more annoying that sorting my mods by Type/Speed & finding my lowest are on some old characters & then having to 1 by 1 go into each character to remove them from the Character then back out to Mods Inventory/Manager & resort by Type/Speed to then SELL them.
