Option to move to "next message" after delete

So, I was able to make MM do this they way I expect by adding the following key bidnings

  "\UF728" = ( "deleteMessage:", "selectNextMessageRow:" );  // ⌦ == delete
  "\U007F" = ( "deleteMessage:", "selectNextMessageRow:" );  // ⌫ == backspace

But then I noted that other behaviors also assume that the direction of movement should always be towards newer messages. e.g. from Standard.plist:

  " " = "scrollPageDownOrNextMessage:"; // Space

Aside - "scrollPageDownOrNextMessage:" does not seem to be documented here:

Try to see if MmMessagesOutlineMoveStrategy solves your problem.

I came here to ask the same question, and setting the hidden preference to "previous" does what I want, thanks!

Also came here seeking an answer for this. defaults write com.freron.MailMate MmMessagesOutlineMoveStrategy -string "previous" solved the issue for me too.

And I discovered Hidden Settings. Even more awesome power below the hood of MailMate. So excited for this application.
