 - What precise workflow do I need for me to be viable to use this?
 - From a user (novice) point of view, how does it look like?
 
+- Show what process/coroutines are running and allow to kill (active process buffer?)
 - ctrl + p like in VSCode (without special buffers)
+    - I THINK WE NEED A SPECIAL VIEW, this is too slow
     - Move to the top so that it can be progressively expanded using coroutines by appending at the end
     - Maybe 2 windows?
 - Guide on the first page for new users with links to configs, tutorials
