Within our company we use a proprietary template engine, which stores its templates in a MySQL database. We recently developed a WebDAV interface for this, which allows us to use standard tools to edit them, instead of a nasty <textarea>
.
The standard operating-system webdav clients aren't great though, so for OS/X we went with Coda, which has amazing WebDAV support and saves us a ton of time.
Some of our devs are on Windows though, is anyone aware of a good editor that comes with built-in WebDAV support?
