Match granularity of app notifications to what's available for email.

I’d like to be able to have more control over the desktop app notifications, similar to what’s available for email. Email offers several options to optimize notifications, but for the app, the only options are either “everything”, which is too much, @mentions, which isn’t quite enough (or none at all, which is definitely not enough. :))

I’d like to have a bit more control to allow some things through—when work is blocked or unblocked is a big one, as we use a lot of dependencies in our workflow and it would helpful to get a note when a task is unblocked.
