My reading list is rather long. Is there any way to filter it based on when the last chapter was updated? For example, "show manga that hasn't gotten a new chapter in 60 days."

If not, I think this would be a useful feature.

Possibilities:
* ALL Scanlation Groups that scanlated this Manga are Inactive.
* The Scanlation Group that released Last is Inactive.
* The Scanlation Group that released Last is Active, but has dropped the Scanlation.
* All Scanlation Groups that scanlated this Manga are Active, but have dropped it.

Reasons for Dropping:
* Got Licensed.
* English Scans available.

Inactive Period Problems:
* Got finished.
* Got finished outside of MU (Dropped, Not eligible to list Release).
* MU does not Track Release-Period of Mangas (Random, Monthly, Bi-Monthly, ...)

If you go to My Lists and scroll down to the bottom, there's an option to "sort by latest release". The most recently updated will be at the top and the last updated at the bottom, though you'll have to open up the pages themselves to see how long ago it was that they were updated. If you just do that a couple of times until you find one roughly at your threshold, you can then delete/move the entries below the threshold from your list by ticking the boxes beside them and selecting "move to --- list" or "delete selected" at the top of the list.

Not exactly what you're looking for, but kind of there.

That's pretty close. Is there a way to further filter out completely scanlated series from the list? If so, that would work perfectly. I guess I could go through advanced search and manually move the completely scanlated series to another list.

Yeah, that's the only way to do it as far as I know.
