  • experimental Greasemonkey functions (GM_getValue,GM_setValue,GM_deleteValue,GM_listValues,GM_setClipboard,GM_openInTab,GM_log,GM_addStyle)
  • you can add a Userscript through a simple Textbox on your device, or you load it by an URL
  • if you open a Userscript in it's own tab with an ".user.js" ending, USI will ask if you want to import this Userscript
  • you can use jQuery in your Userscripts (@include-jquery)
Note: This Addon is still an alpha version, many things will not work properly.

Userscripts written for Greasemonkey won't run sometimes, because of the handling for @run-at defined in the meta block. Try to change it from "document-start" to "document-ready" if some Userscripts does not run.
