Thanks for your thoughtful answer.

- Re: continuously running a notebook server, how about an alias in your ~/.*rc file that just launches a new JLab? Personally I don't find the startup time so high, so it doesn't seem to me 'startup time' is the strongest lead to sell the product. (Of course, if most people find that the startup of a notebook is indeed a large cost then it's a fine point to make. )

- Re: command palette, gotcha. As you say, classic notebooks are going away (and I haven't touched one in a while).

- Re: formatting, I take it back. You're right, there's been plenty of times I've wanted to have nicer formatting in a notebook/lab, that's nice.
