I've acquired 836 mods at the moment. Under the current sorting system, if I want to view mods I have already placed I need to click on each individual character and select the slot I'm looking at and either screen shot the attributes or try to remember them. If I'm trying to compare or evaluate switching that mod to another character... then I need to go back, look at another character slot, back out again, wash, rinse, repeat...

This is a giant pain and seems like it could be easily fixed by adding all mods I own to the panel of possible replacements. This is something I'd love to see in a future update.
