Keyboard support for people and tags

Would love to type @fred on a physical keyboard to have the same UI as tapping the button above the soft keyboard. Likewise #foo to type the foo tag. In fact, just get rid of the buttons above the soft keyboard and use @ and # for entry, just like in Twitter et al.

Love the app!

But this is already how it works, you can type @alex or #sometag to create people and keyword tags respectively.
