[pmw]

Not sure how much I like this. With this algorithm, the user would never see 100% displayed, because at that point the UI would change to remove the progress bar entirely. Whereas seeing 100% feels oddly satisfying, even if inaccurate.

Many TUIs (text user interface) with multiple operations will show one bar reach 100% and move onto the next process (or show multiple in parallel).

If the UI automatically transitions to a totally new screen after completion, I'm never going to see 100% anyways, unless the app does the exact infuriating thing in TFA, which is render 100% (at 99.whatever) and then do some fsync/cleanup and actually be frozen showing 100% which is the contrapositive of oddly satisfying, it's unsurprisingly unsatisfying.
