I played with the setting on Mac to see how it behaves.
Apparently, there, only the "standard" setting is supproted: on Mac it 
is the drawer, on gnustep it is floating (where sas a drawer is anyway a 
floating panel on gnustep, so the distinction is possibly useless).  On 
mac, when other views are selected I can't "open" the mailboxes view at 
all, so I reverted However changing preferences, re-opening the 
application seems to work fine.
