Personal opinion, obviously, but I would really like to see the following as features of a SH/the decorating system:
1) Stances for NPC
One of the things I'm quite disappointed about with the NPCs is that they have fixed stances. Many of them don't fit with a particular theme for a SH, or just look a bit out of place.
What I'd like to see is a drop-down on the placement menu (underneath the X-Y-rotation selections) where you can set the stance of each NPC independant of each other.
Common stances like - "hands up" "pistol/blaster/lightsaber drawn" "standing with hands behind back" "arms crossed" "pacing" etc.
The NPCs would still need to be unlocked through the Cartel Pack purchases, but they would be so much more versatile, and allow people to customise their SHs that little bit further.
Whilst we're on the subject; I'd love to see 'stances' under the drop-downs for the player character too - alongside the 'mood' dropdowns....
2) Choose the spawn location
In my opinion, this is really only an issue on Tatooine (spawning on the Balcony makes no real sense IMHO) - and the Guild Flagships, but it would be nice to allow for characters to spawn at a location via a decoration - only one per SH, and invisible on placement - but it dictates where the character spawns. So if you wanted them to spawn next to a speeder on the Coru/DK landing platform, or to spawn at the edge of the Tat SH, or in the hangers of the Gship, you could.
I expect number two would be considerably more difficult to implement than the first, but I wonder if anyone here would like to see them all the same?
