Greasemonkey script/Extension for viewing giveaways?

Hi there,

Is there a greasemoneky script or extension for the giveaway section? I don't mean for auto entry or the likes, but it would be nice to enter the giveaway on the front page instead of opening up a new tab. It would also be nice to sort/group giveaways by level. Like, it would be great to show all level 1+ giveaways and sort by entry points needed, as an example. Thanks
