Maybe a quite long fixed length (~40 characters) bar would also be reasonable and the dot-time scaled to fit the progress. A progress bar needs IMO two informations: - that it's still working... so a quite frequent output of something to keep me calm. - how long it will take... so I know how much time I will have to get the next cup of coffee to keep me tickin'. Perfect (= close to overkill, I know) would be IMO an additional output like: Programming Flash from 0xc0ldbeef to 0xc0ldcafe takes 112s. ................. | So, I don't need to estimate from the first dots how long it will take to complete.
