I want a beautiful progress bar for my data diffs so I have predictability in my workflow. There are times where I wonder if a data diff will take 10 seconds or 1 hour. Even a simple rule of thumb estimate is better than nothing.

This is not meant to be a "cute cosmetic" but serves to cue when I should stay and watch my terminal or leave to play with my dog while a data diff is running long. Think: save precious time and cue context switching when that's more productive.

During each diff, it shows a progress bar to indicate how long it's taking and estimated completion time in seconds/hours
