// NOTE
// The original ScrollToY was published on userscripts.org by "@namespace henrik.nyh.se"
// It stopped runing and the author was unavailable.
//
// This script now is an updated and altered version of the original.
// It offers a Greasemonkey menu entry to set and save the desired scrollTo-position for the current host.
// HowTo:
// Scroll to a certain position on a given page that you'd like to become the default scroll-position
// whenever you visit that side. Than choose "ScrollTo_setY" from the GreasemonkeyMenu to save
// this specific setting. A simple alert will popup to varify the setting took place. [*see below]
// A setting can be changed anytime by repeating the above described procedure.
//
// enjoy ~ Vivre
// ***********************************************************************
// * Setting:
var showAlert = 1 // assign 0/1 to en-/disable the verifying popup
// ***** Scrolling to stored y *****
