Since mangago has been adding new functions, it would be nice if they added something like a “multi-tag” you know when you search through the tags? Like “glassed uke”/ “tsundere seme”etc? They let you search just one tag at time (quite sad) , what if I want a glassed uke with a tsundere seme childhood friends? That function would be a super thing
