This is only slightly related, but I was thinking of a tri-state
preference option for "Go to next unread message" behavior:
- "no boundaries"
- "stay within one foldertree"
- "stay within one folder"

I myself would be mostly interested in the last setting, since I prefer
to switch between folders manually.

Any opinions?
