Comment 21 for bug 237341

My vote would be to make the groupings work logically by calendar week/month, ie: "last week" is the week previous to this one based on the user's selection in Views > "Start the week on".

I also wouldn't mind seeing John's suggestion of "Earlier this week" (or maybe just "This Week" for a shorter string), etc. It should really be based on the largest logical calendar block though, not just on number of days as it currently is.

..Although I wonder why it couldn't be more granular for old email, if done by breaking out more headings under "Old Mail"? ie (hopefully this displays):

[-] Old Mail
 |- [+] 2008
 |- [+] 2009
 |- [-] 2010
     |- [+] January
     |- [+] February
...etc...
