Tremor Tracker shows a warning on your screen when your tremor totem is dead when you are in an arena. It also puts a warning to party chat whenever a spell is cast that could be broken by tremor, but can't because tremor is dead. It also warns when tremor dies while someone is afflicted by something that it can break.
Slash commands:

The size of the frame can be configured on line 3 of TremorTracker.xml. Just make sure that the x and y remain the same or it will become distorted.
