I implemented something like this in bash. I called this status bar sort of implementation as "message bar" to show the ongoing status of the script on a reserved lines on bottom of the screen - I had to implement progress bar one for each task inline (and not on the bottom bar) - and constantly had to switch "states" to save/restore the cursor positions on screen. This message bar would also become a prompt and take in user inputs on certain events apart from being a static status bar - super useful for the use case. Cursor positions, scrolling screens, events, progress bar updates, managing child sessions, handling screen resolution changes, taking user inputs...everything had to be catered for in this. I thoroughly enjoyed developing this and still think it was a bit over the board for what I was developing at the time but I was sent o

I can't agree more!!!

In short 75% of the code in there is just handling the terminal (keys, scroll, progress bar etc.) and 25% is the actual load balancing logic.
