For the smaller translation groups this isn't a big deal but for the larger groups that have a bunch of titles, it would be cool to be able to go to the group page and have a list of all the works they've translated with the latest chapter number, date posted and the Y/N flag for series complete.
That already exists except for the Y/N part. Group list https://www.novelupdates.com/groupslist/ You can access a group easily too by just clicking them. for example Which will take you to Larger groups have a drop down menu
I kinda forgot I posted this, and then thought I'd check on it. In the case of those two groups, what I'd hope (for WW especially) would be for either 1 page or a series of pages that just listed the series, the latest chapter posted and then a date. I guess a format like the "Reading List" display but just filtered by translation group, replacing "My Status" with "Post Date" or something?
Have you tried clicking on the names of translation groups? It shows all series by them by default and can be filtered by series. Also group news, a link to their site, and fun fact of total releases. Wuxiaworld: https://www.novelupdates.com/group/wuxiaworld/ (I see this has been mentioned before. Your previous request only has the “completed” part not already existing unless you mean changing the pages format completely.)
