Independant state memory for property groups

[donzi]

It would be helpful if the present property UI would save/restore expanded/collapsed states independantly of one another.

EG:

property : [stations & all ship] - [station & subordinates] - [fleets] - [unassigned ships]

..as it is, expanded/collapsed state(s) are shared.

If independant it would offer a way to view, say a fleet in two ways. One (EG: [fleets] with granularity of assigned ships, docked, etc and one with another chosen topology, like fleet (collapsed) commander only for [stations and all ships] filter.
