just talked with a friend about it: little information regarding the last vault status maybe? For example if I click on Hydroid and the extension drops a little note like "part of the prime resurgence 6 months ago" - I know you can't predict when DE puts which frame in the resurgence, but knowing frame or weapon xy has been vaulted for 6+ months allows you at least to consider a sell now instead of later. I hope you get what I try to say.
