[Feature Request] Columns Shared Between Accounts

[PRGilland]

One thing from Tweetdeck I'd like to see return in some form are columns that are shared between multiple accounts, if possible. In Tweetdeck's case, it was the Mentions and Messages columns, where they each had All Accounts equivalents.

Perhaps this could be extended to each of the basic columns, and let you pick and choose which accounts share them.
