There should be release filtering for only English releases and filtering for series genre. I think it would help the readers to find the manga that fit their taste
@Mark551 You can set your language filters by clicking the globe button in the top right and setting the first box to only the languages you want to see.
Filtering by genre is on our list of things to implement. You can find a list of all the things we eventually plan on implementing in our megathread. https://mangadex.org/thread/5101
