The Zone window currently displays:
- Zone Name
- Time Left
- Minimum Duration
- Maximum Duration
If you select a zone by clicking on it, then hover your cursor over the "Reset Timer" button, the tooltip shows you how much time until the zone is resettable.
It would be much better if that info was in the table in its own column, say, add a fifth column called "Time Until Resettable" and then display the time there.
