Many SVN GUIs, e. g. TortoiseSVN or Eclipse's Subversive Plugin, allow people to pick URLs from a tree-like view. This makes it easy and error-free to select the right (possibly lenghty or complex) URL.

It would be great if the Jenkins SVN plugin would allow to pick a SVN URL from such a tree-like view, e. g. the could be a small button right to the URL field in a job.
