This has gotten interesting ... more than the early post-release threads of a similar vein ...
I am almost entirely SP, so that is my basis.
I was hoping for more Force Seeing / Sense. I find it hard to believe that at later levels I'd not be able to stand on one side of a door and be able to know whether I should power off my saber or say 'I have a bad feeling about this ..." I envisioned a level 1 where your Force Power bar would pulse when you sensed someone within say 20 feet or so, only in the open, and perhaps on the other side of a door. Level 2 would extend your range, allow your sense to expand through walls, and have a better feel for numbers. At level 3, you could see through walls.
The dark side power suggestions I find interesting as well ...
