Simply scrolling to top or bottom
A simple scroll button.
Perfect for tumblr or twitter which use endless loading.
you can disable for specific site and your seetings is always synced with Chrome sync (you must check "extensions" in google chrome sync)
This extension has very light code (~ 6k without scroll image).
Enjoys !
