We've been committed to trying to make this easier than it was in the old UI.
For disabled datasources. each device has a disabled group as the first option in the tree. If selected, the level(s) at which the datasource was disabled will display in the tool bar with text "monitoring disabled at ..." The advantage of this is if there are multiple groups where it has been disabled, you don't have to try one at a time. You will see the full list (assuming you have rights to view those groups).
We've put a lot into thresholds recently as well. You'll notice in the upcoming release (v.73) that the hierarchy of thresholds set and the ability to navigate to change them has greatly improved, regardless of where you're editing the threshold from. We do list all the thresholds for each datapoint in the Alert Tuning tab. This displays in the expanded view of a row if you're looking at a group.
If you get a chance, please play around with these features and let us know where gaps remain.
