Have the Vault panel bar as a separate dockable window like the iLogic browser. So that it is possible to view both the model and vault panel bars at the same time.
Also Auto-refresh the Vault status in the panel bar.
This will stop a lot of user errors on usingf the Vault, when they complain of overwriting models etc.
Users are under pressure to "get the job out", many times they don't even look at the Vault panel bar!
If it is easier to see the vault status and it is refreshed automatically, it will make the designers job a lot easier.
