Currently, we can set a filter on the genre of manga what we can't do, is filter specific scanalation groups. I would very much like to have this ability. I have my own lists set to screen out hentai and yaoi. Its fine for the yaoi groups. They're almost all very good about marking their releases properly. And they're popular enough, that even if they don't, other people will very shortly thereafter. However, quite a few groups are big offenders when it comes to not listing hentai on their releases. Little White Butterflies comes immediately to mind, though there are others as well.

Any chance we could gain the ability to filter out specific groups? Alternatively it might be nice to, as others have suggested, be able to highlight other groups so we can follow all their releases too.

Filtering groups is a feature I would like as well. As Molenir states, there are a few groups that I do not wish to see on my update list.

I don't think the problem is with Scanlation groups in general.

The problem is that releases get approved and added by moderators faster than their respective series.

I can add a release and series at the same time.
The release will get approved in a few minutes.. an hour tops. Yet the series can take quite a few hours or even days to be approved or rejected.

You can't exactly filter releases but instead the series genre.
