With a long chatter feed your Account page may inolve lots of scrolling, or hiding the feed (defeating the point of having it!)
To the rescure, this old gem, tabbed Accounts! http://wiki.developerforce.com/page/Tabbed_Accounts_in_30_seconds
The BIG FAIL - mine or Salesforce's ? Can I have my Salesforce1 users see the default layout, not this VF page? I am missing how to make this work on both platforms - please help! Thanks
