There should be an option to change the sound for the saberups, saberhitwall, etc; etc.

There should also be an option to remove the saber glow altogether. This is particularly useful for hilts that are swords.

I agree on all counts. However, I think the best system would have seperate components:

1. Hilt
2. Blade - Color; size; etc. I'd also suggest a "off" button to allow people to use non-energy blades as part of the hilt.
3. Sounds - Create a new config file that handles saber sounds. This would allow you to have set ups like Luke's saber with Dooku's sounds. Sure, it's not "accurate" but I figure people want to create their "own" players and sounds more than be 100% in line with the movies.
