MsgFiler 2.0.8 has been released.
This version is qualified for use on Mac OS 10.6.5, although you may need to re-install the plugin. Recent updates to Mac OS X Mail have a tendency to disable all mail plugins, even if they are compatible with the current OS.
In addition to a general compatibility fix, there is one additional new feature. Many users have been asking to do away with the double press of the Return/Enter key if there are multiple mailbox matches. Previously, if your search came up with several matches, pressing the Return/Enter key would move the cursor from the text input field to the mailboxes pane. You would then use the arrow keys to find your match before pressing Return/Enter to file the message.
Now, there’s an option in the Preferences window to do away with the double keypress. Longtime users of MsgFiler will have to retrain their muscle memory, but try it out and see if this makes filing faster!
