Session Bench
Rims and hubs you want to use for calculations are stored on your "bench". When no user is signed in, the contents of the bench are stored with your browser session, which will eventually expire and disappear after some amount of inactivity. After signing in, parts you select will be added to your user bench, which is saved on the server and persists between sessions until you remove them. Any parts on your session bench can be easily moved to your user bench.
