1) Yes, it would be useful.
2) FreeBSD (desktop? what desktop?), Windows XP Pro, Windows XP Home

Lots more nitpicky suggestions, but I'll save them for later. Do you have access to the beta tester board for PMM? If so, you'll want to browse through it - there are lots of feature suggestions in there from before the 3.0 PMM was released.
