As a plugin developer, I like to try new things in trunk (the development version), and when users give me feature requests, I usually test them there first, and ask the user to download the development version from the wordpress.org repository. However, the development version is at the bottom of the list of "other versions". If you have many different versions, it will not even apppear on the page without scrolling down. It would be much more obvious if the development version were listed at the top of the list.
Thanks for all your great work on wordpress.
