I am all-in for this feature. Main thing pausing on this feature is to find a "stable" way to spy on stdout/err output to keep the line in the bottom. Nothing impossible since we have done it with webpackbar long ago but also tricky to be done right. (We might introduce it as opt-in initially)

Also from the notes in discord chat, this feature need to be customizable and extendable options (with callback) to add something like Open Docs
