I realize my suggestion would be a huge undertaking, but I thought I'd suggest it nonetheless.

A major issue I have when I'm searching for a new manga to read is having to open up a bunch of titles all on separate tabs. I'm not sure about others, but I can usually tell a manga I'll want to read by its cover. Covers are usually pretty telling as far as manga goes. So I wondered what if you could hover over a title which would give a quick preview of the cover or page the url would take you to. This might allow for a quicker and more efficient searching process.

Again, I imagine this would be a big undertaking. But even if not possible now, I thought it might be just fodder for future thought.

Thanks for checking out my suggestion.
