...people can click on older messages to expand, just as in Gmail
Currently, long threads in my inbox are difficult to read because you first have to scroll past a lot of old messages.
This is exacerbated by the fact that the old replies will generally have the full quoted contents of even older replies. So I propose an additional fix: when an email ends by quoting an earlier email in its entirety, we should collapse that part by default. (Gmail does this, but their approach seems somewhat complicated, sometimes resulting in multiple collapsed blocks. I think we can get 80% of the result for a small amount of effort by just checking if the previous email has been quoted verbatim, and hiding it if that's the case.)
