Hey Phillip

Just came by accident across your post.

Super cool that you do a lot with bundles - I want to do more with 
bundles too:

* I am looking for a bundle/command which saves a message to a 
predefined folder without all the folder hierarchy the “Export - Copy 
to Folder” command creates.

* Also I would like to have a bundle to to save attachments to an 
additional fixed/preset location.

One day…

Happy emailing,
