ODB Editor support
Time for a new snapshot...you can download a copy from:
http://code.google.com/p/macvim/
The main feature of this snapshot is ODB Editor support. The current implementation is fairly complete, so all "usual" ODB operations should work. However, some "optional" items are not yet implemented; for instance the window title may point to some temp file when you edit with ODB instead of the remote path (if e.g. it is on an FTP server) of the file.
When trying to set MacVim as the external editor for an ODB aware app please note that apps usually hard-code which editors support ODB. This means that the ODB aware app may tell you that MacVim does not support ODB even though that is not the case.
Another related feature is Xcode integration. If you for example double-click on a build error in Xcode (after setting MacVim as your editor in "Xcode Preferences" -> "File Types"), then MacVim will now open on the line of the error.
Another nice addition is that tabs on Leopard now look much better thanks to a patch by Nico Weber. Another thing Nico has added is support for forking (see :h gui-fork); this mostly means that you don't need to add '&' when starting MacVim from Terminal (the mvim script has been updated to reflect this change as well).
The rest of the changes you can see for yourself at http://repo.or.cz/w/MacVim.git.
