They actually will stay up for a lot longer if people didn't pull early!

Also you can open them up at any time from the Duty window once they closed.

That said, I agree with these points:

* More class ability poses (not just vpose and bstance)
* More eye/look at camera functionality on a lot of the older poses (Huzzah is one that needs it in standard Gpose, too)

I would also add in, for the UI itself:

* Give us the option to keep Portraits open for up to 10 seconds even if some jerk pulls the second Duty official opens. Or just "keep Portraits open until I actually close them."
* Or Give portrait its own keybind on/off option so we could set it as an HUD toggle
