Any way to name a cell without rerunning it?

[louy2]

I often run a one shot cell, and discover that I need to use it later, and I give it a name but it needs to be run again. Is there a way to name a cell without rerunning? Or is there a default name for the cell output?

Thinking it a bit further:

Currently every Pluto cell has an (internal) UUID, which is used internally and in the notebook.jl file, but is not exposed in the frontend.

We could show a unique identifier for each cell in the frontend, but this should be something nicer than the UUID. Some ideas:

• a number, maybe related to cell execution order (analogue to Jupyter)
• a short form of the UUID
• some nice symbol

This cell identifier could then be used for a number of different purposes:

• Use the identifier in other cells to access the cell return value (like in Jupyter)
• For visualization of cell dependencies or execution order
