YouTube Decluttered

This is Greasemonkey user script and Stylish user style for my personal usage.

What It Does

• Minimize the top bars to just YouTube logo at top-left corner

  This is not perfect, I'd just fix them at page top, but unfortunately, YouTube JavaScript scroll down to fixed position, for instance, switch to user's videos tab. If the top bars are fixed at page top, the scroll wouldn't be perfect.

  This also left a significant amount of blank spaces at top.

• Kill the channel trailers
