Chiming in with another vote for the ability to "follow" authors and/or artists, or set up some kind of alert at least if they start work on a new title.
I was reading Shomin Sample, which got the ax, but it was kind of charming, I'd still love to see what else the author or artist might come up with. Plus if Tsubana comes up with something else, I'll definitely want to check that out too.
