Cloning Views 2 Displays
We're working on a site at the moment that has got lots of very similar block views. While Views 3 has the ability to clone displays, we're stuck with Views 2 due to compatibility with a version of CiviCRM.
In a bid to avoid having to create each block view from scratch manually, I stumbled across Views Clone Display. This lovely module lets you clone displays in Views 2, saving lots of time. I only wish I'd found it sooner!
