A few suggestions of mine:
-When loading a saved gear missing charms are referred as numbers:"5x533 not found." Would it be better if changed into charm names?
-The "add all charms to deck" mark(default as #) is ugly and no matter what char used. Can it be set as, e.g., shift+left click the original mark(+)?
-Loading all charms into the "gear" page is a slow process especially on outdated computers(like mine..). Could there be a local storage of charm infomations(like a menu, or reference), and query the specific charms infomation only while composing a deck(like ordering food)?(Not very much understanding the machanisms, just a suggestion.)
-Show exact expiration time for very old items in temporary storage(red & yellow in time indicators)?
