When you watch group info you can see which series they have worked on. It would be nice if I could see which of these series are already on my lists. There are certain scanlation groups from whom I try to read all series they are working on (though not necessarily on a daily basis) So if a series is on a completed list, show the green check sign in front of the series name, so I won't have to check this series anymore. In this way I can periodically check series from scanlation groups that are not on any of my lists.
yea, the series list at the bottom of the group page.
i remember most of the series names that I've read, but for stuff like oneshots that end really fast you usually don't get a big impression and so you forget the names. if you implement the list status on the group page it would really save some time =)
