Hi @ginobean!

Thanks for reaching out. Always interesting to learn what commands are missing and which ones should be prioritized.

I been doing a lot of looking into shells there are others library and tools that have a lot of commands already built into them. It is a shame it looks like this project isn't open source(I can't find it); I would like to see if I could improve the shell ,it is awful and the number 1 reason I can't use stackblitz. I keep jamming it up (probably because of the lack of commands).

There are many things that might help you improve your shell here is a list of some

If you are interested I would try to add more but it greatly annoys me that webcontaner doesn't appear to be opensource.
