As an aplication developer I would like to have graphicall diff for comparing files

I found textual diff for Subversion, but it would be nice if there were graphical diff also. The following features would be useful:

• graphical diff to compare file content (current file with based revision to see user changes)
• graphical list of file history (allowing to select revisions to be compared)
• graphical list showing changes in repository (listing files that differ with head/or based revision and allowing to open option for comparing changes)
  I think good reference is Eclipse subversion plugin, options in "Team".

How to reproduce:
1. Create projected based on repository from subversion
2. Go to Tools/Subversion/DiffRepository or Tools/Subversion/Diff "myfile.cpp"
3. svn diff opens in editor window, but diff is in textual mode. It would be great if application developer could use graphical diff.
