Currently for every repository there is a large description field that can be entered. This would be better and more portable to other apps (bitbucket, github) if the overview page would show a README file as part of the overview.
Since so many people (including myself) are using Rhodecode instead of (or in addition to) services like Bitbucket and Github, this would create more portability between them all.
First stab at it doesn't have to be complex, something like just using (by default) an available README (or README.md markdown file maybe). From there it could handle more formats. Just a suggestion.
