Then line buffer stdout and stderr to the same UI element, and also provide an option to toggle showing just one or the other. Sounds pretty useful to be able to switch between just showing one or the other, and showing them line-interleaved by timestamp, even if you do want to default to the latter. If line buffering isn't enough, you can use heuristics around read sizes and non-blocking reading to guess whether a given write to the pipe was intended to be done as a block.
