Oh for sure! Not trying to get on your back, just agreeing from a UI developers pov :) I seem to have misunderstood your original intent but we’re saying the same stuff I think

I do often desire a “click to continue” option, especially helpful for asynchronous tasks. Start a render, and when you get back it says 100% without you having to look at the output folder, for instance. I get what you mean though, it certainly should say 100% unless it’s totally donezo. Probably lazy rounding errors in some cases (Microsoft products are the worst at showing accurate progress bars)
