You should be able to search two tags at once. I understand you may already be able to do that with advance search, I could not get that to work, or it is unclear how to do it. Maybe make it more clear, or just put a place (after already in a tag) to add another. Example: I am in the Full Color tag, and I want to find something in full color with feet, there could be a button where you put another tag. Or something of the sort. Make it easier to narrow down the choices, or help find a mores pacific category of manga.
