What is an "interactive matrix viewer"?

My guess is that this might be something that allows easy input of a matrix, as with the graph_editor? That would certainly be useful (in TeXShop I use something analogous all the time to relieve the tedium of typing in LaTeX matrices). Don't know for sure, though.

Well, we have input_grid (both in SageNB and Jupyter) which can do this. The only potential caveat is that the size is fixed: you need to specify the number of rows and columns in advance.

In interacts, yes? Maybe this was originally opened to allow this outside of interacts ... honestly I don't know, but your caveat sounds like a reasonable goal for this ticket.

Right... the thing with Jupyter widgets is that one can use the widgets without interacts. Essentially @interact is built up from widgets, for example setting up the auto-evaluation when a widget changes.

With SageNB on the other hand, controls (the SageNB term for widgets) cannot live by themselves. They require @interact to be used.
