a good new improvment in your good application would be to add support for "svn copy".
today a file that has been svn-copied shows a truncated version tree (due to the --stop-on-copy option).
the simplier solution could be to add just one box a the tree root saying that the file has been created from the other file at the revision rev.
the information can be retrieved with a command like:
svn log myFile -v --stop-on-copy |grep myFile
which gives the following line (among other lines):
A /repository/path/myFile (from /repository/path/myFileOrigin:25)
another more complete solution could be to add the version tree of the copied file at root (perhaps with another colour).
Logged In: YES
user_id=18012
Originator: NO
These are good ideas but I think it will have to wait until after the upcoming bugfix release.
