// @name           Tradera enhanced watch list
// @namespace      http://henrik.nyh.se
// @description    Makes the Tradera watch list more usable. Puts the list above the page text, adds thumbnails and removes cruft. Coming later: autologin, Remindera integration.
// @include        http://www.tradera.com/trader/trader_memorylist.aspx*
// ==/UserScript==

/* Todo:
	- ett-obj-xpath
	- autologin
		@include        http://www.tradera.com/login.aspx?url=*trader_memorylist.aspx
	- removed "filter" for convenience - might change this later
	- get e-mail from http://www.tradera.com/trader/trader_change_email.aspx and use for Remindera integration
	- add-to-list-and-bounce-back?
