As a reminder to those who forget or are learning the system, when seeing the "rename card" button and it's grayed out, it's not immediately intuitive why. You have to remember that rule. Could you add an indicator to remind the user why the asset is grayed out? At first, I thought it might have been a bug because I used the card, then removed it, and maybe some flag was set that prevented renaming. Or maybe it was an option that the narrator has to keep a card from being renamed.
