Do you mean that the user might do something on the wrong connection, or that the Toad system itself might perform something incorrectly?
In my opinion, the user will not get confused, because they always see in the Windows Bar only the items related to the active connection.
Both, but it becomes a non-issue if the active window's connection = the active connection in Toad.

If the "current connection only" option is enabled, which it may not be.
