Subcommander is an easy to use, cross platform (Mac OS X, Unix, Win32) subversion gui client including a visual diff and merge tool.
What's new in Subcommander
new: bookmark icon animation for running commands (so far only used for working copy status).
new: status filter to hide modified, added etc. items from the view. This is still imperfect though because of the way the view is populated.
changed: it is now possible to copy multiple items at once in the working copy and in the repository (multi-selection).
changed: to move/copy files to a folder it is now possible to drop them on a file inside the target folder and not just directly on the target folder. If the target is a file the files parent folder is used as the target.
