1) tag referring to RSS feeds for journal on all project pages This would allow extremely easy subscriptions even from Ohloh.
2) Commit count graph on project's Commits page Just like personal commit count per project can be seen on person's profile, it would be great if same could be seen for entire project. I am referring to "Commit Timeline" on profile pages. By the way, I'm certain there was some (different and interactive) kind of commit timeline for projects. Unfortunately I cannot find it anymore. It would still rock if you guys had the non-interactive variant, perhaps even as a widget.
3) Commit RSS I have found some script that takes SVN's XML output, parses it and XSLT-transforms it into RSS, and I've cronjob'ed it on my server. However I'm sure many projects would find it useful, even with several days of delay.
Of course it might create some extra impact on your servers ... you could reduce it by setting feed's TTL to one day or more.
4) See files distributed under some license for a project I haven't found a way to see which two files are licensed under LGPL in project "yatc". Of course, I can do the search and all ... but that's easy because it's my project. Still, it would be useful in tracking incorrect license detection, or in seeing which files are exactly incompatible with GPL, etc. And it would be very useful when looking at other people's projects.
Awaiting comments :)
