Source code is easy to read with function bookmarks, word search and various theme and font choices. You can add notes to code and email them along with the file or from the Annotations section. On the iPad you can split the screen to view more than one file, the revision history or the differences to a different revision if the file is under version control.

Subversion support includes checkout, update, log and, only on the iPad, blame, and diff. The supported repository access schemes are svn, http, https and svn+ssh.
