I've blogged about how you can restyle VideoSift.com using FireFox and either the addon Stylish or GreaseMonkey a couple of days ago. Since then I've made a few more versions sporting different colors.

Update: I've worked out some of the problems with the Dark Style. I've also added to all of the styles to make them work in conjunction with my InvoMerge script (screenshot).

One word about the dark theme: I had to "tone down" the charter comment background colors, because they were too bright for the dark theme. I didn't want to sacrifice the individual backgrounds, so I tried to achieve the best of both worlds.

Enjoy!
