[cosmetic] `top` doesn't restore IEx prompt colour :)
[super-duper-low-priority-cosmetic-issue]
See attached image. Should be a real quick fix for knowledgeable Dev :)

We're in the process of updating the top command to be more useful. For our next iteration, I want to improve the colors too, so I'm going to leave your issue open so that I don't forget to test with a custom prompt color.
@fhunleth thank you !
test with a custom prompt color
To be accurate, I was just using the OOTB colouring that IEx uses on a PuTTY (v0.75) SSH window . . . ( I think but will check )
Hey, while you've got my attention 😉 :
A nice top improvement for me is to make the display wider ( so I can see more of the process name ! ) ❤️
