I decided to have a go at trimming down the list of my subscribed threads just now and hit something that would be useful to improve; though it's obviously fairly low priority as I don't imagine too many people bother
You are able to filter down the results to a specific sub-forum, but when you delete an item it forgets the filter and returns you to the full list. Is it possible to update this to that it remembers your current filter selection when managing items please? Alternatively, adding the ability to unsubscribe from multiple threads at once would alleviate this issue.
