This isn't really needed, but it's just an extra tweak and would be really helpful.

First off, a "revealed" or "unrevealed" option would be nice, would help filtering unrevealed vlfs out if needed.

Along with that, a fertility percentage tweak. It could work sort of like the age option. Ex: Exactly/More Than/Less than %. It would help many find actual low fert VLFs such as 1%s, and would overall be a useful little tweak. Would filter unrevealed lionesses out.

I'm super tired and thought this would be a good idea lol let me know if you disagree!
