I hope that stardock won't be upset with this... but I made a little program that lets you work with bootskin ini's graphically. You can load up an ini, easily position the progress bar and set the width for the animation loop then save it. Simple concept, but atleast you don't have to go crazy over positioning by trial and error. It's still a beta, and I plan on adding some more features, but let me know what you think of it, and if you find it handy.
