When press enter on empty indented bullet, should take you to beginning of line

[sachinrekhi]

Love that you've added the convention of pressing enter on an empty bullet clearing the bullet. Improves productivity and mirrors the experience in Google Docs, Word, Evernote, etc.

One nit is that I'd love to see the interaction improved when you press enter on an indented bullet. Today it simply removes the bullet but keeps you indented. So I still have to hit delete several times to get back to the beginning of the line. I think the intention is to always end the bullets and begin at the beginning of the line, so don't see a scenario where I'd want to stay indented. Google Docs has this behavior of returning you to the beginning of the line.

Alternatively if that ends up being hard to implement, then at least having enter mimic the delete behavior on an empty indented bullet would be helpful (in that enter unindents the bullet one level just like delete does). Word has this behavior of simply unindenting one level on enter.
