It works but it just feels cluttered and confusing.

This is true but I think the idea and functionality are great. So maybe with a little cleanup I think it could be one of the better/more useful bootstrap oriented sites that I've been seeing on here lately. At least from a developer's perspective.

Agreed. Some of the fields could use better labeling. For example, there are three font color settings, and the only way I could tell what each field affected was to enter red, green, and blue then view the results. Plus, it needs another field for the hover font color.

I like the idea of advertising yourself on the top of an app like this.

I like this. A lot. It reminds me of Bret Victor's talk on being able to see what you're changing in a design live (http://vimeo.com/36579366).

The UI could use some work though, it's cluttered.

I had the same idea the last days, but did not find the time to create it. AWESOME u did it. Thanks and i wish u success with it. i am definatly going to use it.

This is great! I was actually starting to build a similar tool to customize bootstrap styles, but I think I'll just start to use this one :) Good work.
