1 - automatic linking
2 
3   would be nice to transform the URLs in the mail' body into clickable
4   links.  Additionally, it would be nice to support the [n] reference
5   syntax.  Maybe turning also commit ids into links?

8 - clarify date ranges
9 
10   Threads are sorted by their newest mail, so if an old thread gets a
11   new reply it'll jump in the first page.  The date ranges thus can
12   jump quite a bit when navigating backward/forward.  Is this OK?  Can
13   we communicate it better?

16 - use UTC consistently
17 
18   msearchd uses UTC, while the rest of the UI uses the localtime of the
19   sender.  In the mail page it is fine since we show the zone offset too
20   but the index pages don't show that!
