I was wondering if it'd be possible to implement a way to search by number of days since last update, similar to show only manga/show only items on my reading list -- in this case, show only titles released in the last ___ days and show only titles released before ___ days ago.

Also... would it be possible to implement a way to search by length of series AND by number of volumes completed?!?! By this I mean a few different and complicated things; for example, if you only wanted to read a series that had 30+ volumes, or if you only wanted to read one that had 30+ volumes scanlated, OR if you wanted to only read something that only had a few volumes left, the search system would subtract the scanlated amount from the total amount and give you the amount left and/or a percentage of how much was scanlated... （・∀・）

Thanks for your time (´・◡・｀; )
