Save more than one attachment at a time

It would be nice to have a button to save more than just one attachment at a time
like shown here:

And please line up the E-Mail-addresses and the date.
Maybe give it a light background and bold the subject.

If you meant to open/save all attachments together it is available if you right click at one of them and choose Save/Open All Attachments.

by “more than one” I would like to save attachments of “several selected messages in one folder”. Possible?

Of course, simply select all attachments you want to save and then right click on a selected attachment and choose Save as.
