UI is not easy to use when list of Releases become long. They are sorted alphabetically currently, in descending order. This is not particularly intuitive, especially for the way users tend to use the more recent releases.
Design some improvements around this long list.
Suggestions: filter by most recent by default, allow user to change sort by name or by date added (modified?). Paginate? Show created/modified date in the bar on left next to the Release name.
