Secondary sorting in non-project hierarchy [A: determined by sidebar order of projects.]

I have a perspective in which “Don’t use project hierarchy” is checked, as is “Sort actions by Flagged”.

I like having the perspective automatically move flagged items to the top of each project … but the unflagged items in these projects are sorted in some manner I cannot figure out. I was hoping to be able to sort them manually, but cannot. So how are they sorted?

Late to this thread, but in case it’s still helpful: the secondary sorting in a perspective like this is going to be the same as the sidebar order of the projects those actions are assigned to. In other words, if you open up a second window and select the Projects tab, it’ll be easier to see what’s going on. Hope that helps!
