Customize your Browsing Experience with TamperMonkey

"Android: Moving from the desktop, where you may have your favorite userscripts set up, to your Android phone, where you're missing all of them, can be painful. TamperMonkey is an Android browser that has full support for userscripts, and allows you to add and manage GreaseMonkey scripts to your Android device."

If you've used GreaseMonkey at all you're love this.  TamperMonkey for Android, now in beta, will let you use your GreaseMonkey userscripts with your Android browser.  Userscripts let you modify a web page as it loads every time it loads anyway you want that is possible with Javascript.  You can create scripts to do all kinds of things like change the formatting of a page, highlight specific text, add and element, or remove an element.  These userscripts can be applied to a specific web page or to a group like a domain or all pages.  I'd love to hear some of the uses you come up with for TamperMonkey and how it saves you time on your Android device!
