De-uglify user interface

[regexident]

NinjaKit provides several options for beautifying its scripts. A nice extra feature.

However a way more urgent need for beautification is found in NinjaKit's settings interface. It is more than just ugly. NinjaKit should use a GUI resembling the one from ClickToPlugin.

For a quick look at ClickToPlugin's settings GUI: http://hoyois.github.com/safariextensions/clicktoplugin/#settings

ClickToPlugin's license would allow you to basically it.

Q: What license is your code under? A: None. Feel free to use it in any way. (http://hoyois.github.com/safariextensions/clicktoplugin/support.xhtml)
