Quban 0.6.2 is in development at the moment.
The main addition will be the ability to group articles with similar names together and display on one line in a newsgroup's header list. This single entry can then be expanded to reveal the articles that have been grouped together. All artcles can be downloaded or deleted from the grouped article or articles can be manipulated individually.
This will be an option for each newsgroup, it can be switched off for some or all groups.
I'm also making numerous changes around the interaction between threads to resolve some locking and connection issues.
The way that things are looking with other commitments it's likely to be released in November ...
