GitHub Wiki updated Bookmarklet (Sep 2014)
Note: Will not work with Firefox, see bug #866522
Wiki - Hides extra panels:
javascript:(function(e,a,g,h,f,c,b,d)%7Bif(!(f=e.jQuery)%7C%7Cg%3Ef.fn.jquery%7C%7Ch(f))%7Bc=a.createElement(%22script%22);c.type=%22text/javascript%22;c.src=%22https://ajax.googleapis.com/ajax/libs/jquery/%22+g+%22/jquery.min.js%22;c.onload=c.onreadystatechange=function()%7Bif(!b&&(!(d=this.readyState)%7C%7Cd==%22loaded%22%7C%7Cd==%22complete%22))%7Bh((f=e.jQuery).noConflict(1),b=1);f(c).remove()%7D%7D;a.documentElement.childNodes%5B0%5D.appendChild(c)%7D%7D)(window,document,%221.3.2%22,function($,L)%7B$('%23header,%20.pagehead,%20.breadcrumb,%20.commit,%20.meta,%20%23footer,%20%23footer-push,%20.wiki-actions,%20%23last-edit,%20.actions,%20.header,%20%23wiki-rightbar,%20.gh-header-actions,%20.sunken-menu-contents,%20.site-footer').remove();%20$('%23files,%20.file').css(%7B%22background%22:%22none%22,%20%22border%22:%22none%22%7D);%20$('link').removeAttr('media');%7D);
Wiki - Removes margins too, so the content is wider:
javascript:(function(e,a,g,h,f,c,b,d)%7Bif(!(f=e.jQuery)%7C%7Cg%3Ef.fn.jquery%7C%7Ch(f))%7Bc=a.createElement(%22script%22);c.type=%22text/javascript%22;c.src=%22https://ajax.googleapis.com/ajax/libs/jquery/%22+g+%22/jquery.min.js%22;c.onload=c.onreadystatechange=function()%7Bif(!b&&(!(d=this.readyState)%7C%7Cd==%22loaded%22%7C%7Cd==%22complete%22))%7Bh((f=e.jQuery).noConflict(1),b=1);f(c).remove()%7D%7D;a.documentElement.childNodes%5B0%5D.appendChild(c)%7D%7D)(window,document,%221.3.2%22,function($,L)%7B$('%23header,%20.pagehead,%20.breadcrumb,%20.commit,%20.meta,%20%23footer,%20%23footer-push,%20.wiki-actions,%20%23last-edit,%20.actions,%20.header,%20%23wiki-rightbar,%20.gh-header-actions,%20.sunken-menu-contents,%20.site-footer').remove();%20$(".has-rightbar%20%23wiki-body").css("margin",0);%20$("%23wiki-body%20.markdown-body").css("margin",0);%20$('%23files,%20.file').css(%7B%22background%22:%22none%22,%20%22border%22:%22none%22%7D);%20$('link').removeAttr('media');%7D);
Wiki Edit in Zen mode - makes the editor full width:
javascript:(function(e,a,g,h,f,c,b,d)%7Bif(!(f=e.jQuery)%7C%7Cg>f.fn.jquery%7C%7Ch(f))%7Bc=a.createElement("script");c.type="text/javascript";c.src="https://ajax.googleapis.com/ajax/libs/jquery/"+g+"/jquery.min.js";c.onload=c.onreadystatechange=function()%7Bif(!b&&(!(d=this.readyState)%7C%7Cd=="loaded"%7C%7Cd=="complete"))%7Bh((f=e.jQuery).noConflict(1),b=1);f(c).remove()%7D%7D;a.documentElement.childNodes%5B0%5D.appendChild(c)%7D%7D)(window,document,"1.3.2",function($,L)%7B$(".fullscreen-container").css("max-width","100%");%7D);
