Fisheye doesn't seem to recognize when a file has been renamed in svn. I renamed a file "tada1.png" to "screenshot1.png". It recognizes that tada1.png has been deleted and screenshot1.png has been added, but in the folder structure on the left, and in the changelist summary, it does not recognize this as a rename.

Yet on the revisions page (see fisheye02.png screenshot) it recognizes the file has been moved.
