I've seen some thread awhile back about advance filter and clickable tags, but it never garnered attention. In my opinion, it's kind of weird to not be able to speed up browsing experience given that the amount of comics are absurdly high. Not sure why this is never a priority, webtoon seems to avoid providing advance searches as well, I have a speculation but I rather not say it so I don't sound controversial.
On topic, I think this feature is nice to have but not sure who will benefit from this, will it be the same already popular creator or will it be the reader, I'm not quite sure, but I don't see any smaller creator will benefit from this. If this feature anyhow will help smaller creator to get better exposure, I'm sold. Just my 2 cent.
