This might have been suggested before, but I'm wondering if SE could implement a Book of Glamours (or whatever fancy name you fancy) for us to store a "visual copy" of the gear we've obtained. Say you've gotten a Battlemage's Robe from Brayflox's Longstop. Right-click > Record to Book of Glamour. And you can then do away with this piece to free up inventory space.

This book can display recorded gear according to location / sets, or categories like Head, Hands, Body, Feet, etc. Allowing collectionists to complete sets or even adding related achievements can encourage doing past content.

The only thing I'm really afraid SE would say is the problem of database space, since recording which gear you've obtained surely takes up valuable space... :< Glamour is important to a percentage of the player base, and with SE's effort in adding glamour-related content to in-game events and even the cash shop, I really feel they should seriously consider implementing this.
