preconfigured columns for newbies
It would be a help for people who lack the time to individually set up their columns. This enables them to sort all their networks at once according to the direction of the message.
Example: Mine are > Stream (Twitter home feeds, Facebook newsfeed, Myspace friend statuses), Sent ((re-/)tweets by me, and my favorites), Inbox (my tweets rt'ed+mentions and direct messages inbox), Out (direct message outbox) and Scheduled.
Whenever you add a new social network profile, some pre-made streams are already created to make your HootSuite experience much easier.
