After being sick for 2+ weeks and forgetting everything about my new code (I wish I would've commented more), I decided to work on a couple side projects until my motivation to continue PhysicSim returns. My apologies..
Done for the most part with the options frame, although i should add a reset button. It should be easy to do but i'll do that for the following release. But anyways take a gander :P I think it's a good improvement from the previous versions. Oh and by the way this would be my first time using layouts.
I made a lot of simple methods to make the process a lot cleaner and intend to set it up for easy additions, the UI is practically complete and If I put much work each day into it then you could expect it in a week. Don't get your hopes up heh
