Problem

In most collaborative editing applications, when a user is typing, their name appears over the cursor. This is a really helpful (and now expected UX) when collaborating in documents. This allows everyone to know who is making the current changes as they appear.

Jupyter collaboration doesn't do this. It only shows a name when you hover over the cursor. There are some improvements to that behavior we can make too, highlighted in #259.

Proposed Solution

We should change Jupyter Collaboration to always show the user's name when they are typing.
