Hello BioWare!
Water things!
So my suggestion is pool from the supplies area of the Republic Fleet.
You can see it on my screenshot.

I know, it's pretty big but you can make it more smaller.
I hope you'll add some decorations with the water.
Holo-Statues!
The second thing is Holo Statues of legendary heroes: Revan stands with his loyal team (Bastila, T3-M4, HK-47, Carth Onasi, Zaalbar, Mission Vao, Juhani, Jolee Bindo, Canderous Ordo)
Something like http://cdn.dbolical.com/videos/groups/1/13/12717/Knights_of_the_Old_Republic_-_ending.mp4.jpg
Music!
Ah, I almost forgot.
Please, BioWare.
Add function to play music from the fleet!
I dont like that cantina music so that will be good to have a quiet music in my StrongHold.
Thank you for your attention
