Is it possible to consider improvements?

[babyboombros]

1- When the option "one file per message (maildir)" is chosen, and a message is moved to a "local folder", a file is created in a folder \Name\Inbox\Cur.

This file has no extension.
Is it possible that the add-on automatically adds the .eml extension to the file? Because if I do it manually, can I open the mail.
Or can we consider an improvement that would save the mail in another format, for example PDF?

2- When a mail is moved to a "local folder", it is saved in \Inbox\Cur\ with a file number to formatting of the name.
Is it possible to add an option to set the file name instead of the number?
