@hugovk @AA-Turner @savannahostrowski any chance you could give this a go? Most of the diff is tests. You can focus on the main TUI code if you prefer. Even if you just test it locally it will help a lot!

[lkollar]

This is super cool! I've not reviewed the implementation thoroughly but I played around with the TUI and everything is working really well. Left a bunch of suggestions.

@lkollar i fix all your comments and clean the code a bit and added even more tests. I also added some color diffing to make it easier to spot changes. Can you give it another go?

[savannahostrowski]

This is so slick 🔥 ! I played with this a bunch and the UX is very solid. I have one comment about an edge case I ran into and one suggestion (but it looks like you're already thinking about export so that's great)!

When you're done making the requested changes, leave the comment: I have made the requested changes; please review again.

[pablogsal]

@savannahostrowski I have addressed your comments and I pushed a new one ensuring the TUI (most of it) still works at the end in a way that makes sense. I left some comments regarding the exporting situation but we can surely explore that on a different PR :)

Thanks a lot for the review ❤️

[savannahostrowski]

Tested out the fix for toggling help when profiling ends and it looks good!

Nice work on this one! Very, very cool! 🚀

I think we are missing something in the makefile will take a look
