We have several Revelation databases in a Subversion repository. Due to Revelation's binary format it is unfortunately difficult to compare them e.g. with diff. This makes reconciling conflicting changes a tedious task.
That's why I'd like to suggest a new optional database format that can be selected when saving a database. Non-critical information like user names, URLs etc. could be stored unencrypted while passwords could be encrypted and ASCII-armored. The file format could be e.g. XML (well suited for Revelation's hierarchical structure) or a custom one record per line format (easier to diff).
