(using e.g. the code from > notmuch-show). I might make debugging easier. Yes this is easy. There are several possibilities and I am not sure which is best (some are clearly bad but are worth mentioning anyway). 1) have a single buffer for part errors; this would accumulate stuff and output seems to get interleaved so this is probably useless. 2) have a buffer for each part viewer as you describe. 3) have a buffer for each part viewer but start its name with a space so it doesn't show up in buffer lists but is findable (maybe) 4) stick with just the temp buffer approach Also, we could have it togglable with some sort of debug flag. In some senses 3 is nice but you would probably end up with 10's or even hundreds of hidden buffers which seems bad. In 2 you see them so you probably kill them as you go but I think they would be pretty annoying. A key difference from the accumulated show/search/pick buffers is that, at some point, you did want to see those buffers. Since all these approaches are easy to implement it is really up to us which we want. Any thoughts?
