We've just upgraded to the latest YouTrack 5, lots of nice enhancements and polish :)
Something we were eager to make use of was better integrated support for estimated story points, however the current implementation doesn't appear to work with our agile process.
We have an estimated story points field at the 'user story' or 'feature' level. Each of these features has story points estimated against it.
We then create tasks under each feature, but don't estimate them.
The current YouTrack 5 implementation appears to only work if tasks are estimated, rather than features. Is this correct?
