// @include        http://fogbugz.root.net/fogbugz/default.php*
// ==/UserScript==

//
// This script will make fogbugz make a bit more sense:
//
// - Rearrange edit mode, to put the title, project, and area, in with all of
//   the other edit fields.
// - Remove the picture of the day.  I'm a coder, not an art gallery curator.
// - Remove the separate headers, to put the list view back into one table
//   when sorting by priority.
// - Nail down text areas so they don't shape shift.
// - Subscribe to all cases that I have participated in.  I need to know when
//   they change to do my job, dammit!
//      (You'll need to put your name in, to make it work for you.)
// - Replace link to "download" screenshots with a way to just farking VIEW it!
//   I don't need to save that crap to disk, with the multiple clicks that takes
//   just to click a few more times to lanch it in a viewer, and a few more
//   times to delete it.
