Sorting by last release

[Beregorn]

This is a thing I have noticed since a long time, and I don't know if it's something you are already planning to fix.
Anyway, the "sort by last release" function index the results by the last release in ANY lenguage: obviously, what I would expect from the function is to sort by last release in MY lenguages. I don't care if the Turkish community released an update yesterday, I want to know if there are new chapters in a lenguage I can read.
