Oh, sorry - I didn't explain myself fully enough! There's no option to group-by-folder (though you can mail the ninjas to request it), but group-by-project starts at the top of the list and works towards the bottom in the same order you see in the sidebar of Context view.
In other words, my suggestion puts the actions all in the same order you're requesting; the grouping is just a bit different. Definitely mail the
support ninjas, though, and we'll make sure to record the request to group by folder.
