Sublime SVN currently supports almost every SVN command. Commands like Branch, Merge and Resolve prompt with relevant information to allow the user to interactively choose the correct action without having to memorize previous actions, or the current state of the working copy.
Applicable commands can be run on the current file, folder or the whole working copy. The Diff command allows specifying custom revisions, all commands can be re-run after editing parameters and custom commands can be run at any time.
The following commands are not implemented: Export, Cat, Import, List and Patch (1.7+ only).
