Wow! So nice!

What gives a cell its name? Is it just the first unique token contained in the cell?

Cell names come from assignments, they’re whatever appears on the left side of an equals sign at the beginning of a cell. If a cell doesn’t start with “something = ” then it won't have a name at all.

Not an intuitive solution, I need to say.

It would be great if this cell could load a different, less commonly used library. I regularly use /demo to test code. "d3" not being the full library here is a frequent gotcha for me, and I imagine for others as well.

Good idea. Switched to he, an encoding library.
