How to widen "Window List Item" boxes in (Cinnamon) Gnome Desktop to fit?

I was able to hack this functionality into the code of cinnamon 2.2 running on debian 8. This should also work on Ubuntu, maybe the path is a bit different.

  • open this file in an editor /usr/share/cinnamon/applets/[email protected]/applet.js
  • find function _getContentPreferredWidth: function(actor, forHeight, alloc)
  • change alloc.natural_size = 150 * global.ui_scale; to alloc.natural_size = 350 * global.ui_scale; where 350 is your desired width.

Good luck!
