1. When are trophies triggered? I just added 10 new trophies and none of them are being assigned. (Edit: They're assigned when you log back in. I really don't like that. You want trophies to be triggered as the action is being given, to provide immediate feedback to user and keep them excited. If user doesn't receive trophy until next login, they've already left website!)
I think you should follow Automation Rules and add criteria for when action is triggered (eg. next post, next reaction, log in, etc)
2. Bug - when I copy a trophy, the criteria are not copied.
3. Notifications - need to show the actual trophy icon, not a blank user. This is boring!
4. Hide - What does hide / unhide do on member's tab? I can still see hidden trophy on member's tab when logged in as another user.
Also, if you hide a trophy, I think you should add CSS to make entire box red like when hiding something in IPS forums
