The latest version of AutoNotification includes the ability to completely block (and un-block at anytime) notifications from specific apps, along with further criteria such as Title/Text. The big benefit is that even though they're blocked, AutoNotification can still pick up on them by using its "Intercept" Profile Event.
However once you have a bunch of blocks setup, it's easy to lose track, and although AutoNotification includes a "Query" for any blocks, all data is returned in Tasker arrays and it could use a good way to better visualize it. Hence the creation of this Helper Task.
When run - this Task will display a list of all Apps whose notifications are currently blocked, including any specific criteria such as Title/Text:
To then un-block any app listed - simply click its listing, and a confirmation dialog will appear for you to confirm the unblock:
(Also all the Dialog colors are easily customizable in the first Action).
