TBB OS X: Last directory recorded in /Users/User/Library/Preferences/

It's not a huge big deal, but worth mentioning TBB 3.5 OS X leaves a record of the last download directory in org.mozilla.torbrowser.plist:

NSNavLastRootDirectory --->/Volumes/place/place/

Some say there is no security through obscurity, correct I'm sure, but no need to specifically point to the directory or volume (even if encrypted) about where data via Tor is being downloaded to.

Seems to be quite a challenge to lock down TBB on OS X. Has anyone checked the status of things like /var/folders lately ?
