Sub-sort function in Manga section

If I recall, when you click like, manga---> sort by: series (for example), then click one of the category there, there is one more "sort by" button that includes "sort by: language" in the past. But since about a year ago or so (? I don't remember), it seems like that function is removed.

I would really like if that function is added once again. I mean, for example, when you search Original Works, and you wanna sort it by the artist name or language or anything, would it be more convenient?

I think that's all from me.

Yes, I used that feature a lot when it was still around but now its gone and going through the manga section is a real pain now

Isn't all this all in the drop down menu next to the Manga tab? Or am I misunderstanding?

No, not that one.
For example, you click the drop down menu next to the manga tab, and choose sort by series. Then, there are another drop down menu as well there, sorting menus like sort by language, sort by authors, etc.
I mean, it would be really helpful to search through the original works section, as we can sort it by the series AS WELL AS by other filters (such as languages).

Oh, or maybe filter function is nice, I'll post later.
