Great product, exactly what I have been looking for, however I have one question regarding the categories.
Is it possible, or planned for a future release, to have nested categories? We are looking at using this for a notification type application where people can subscribe to a particular category, but rather than having something such as;
Category 1
Category 2
Category 3
Category 4
I was wondering if its possible to nest the categories to allow a user to subscribe to the top level category and all nested, or just a nested category such as;
Category 1
`- Nested Category 1
`- Nested Category 2
`- Nested Category 3
Cheers
