A Whole ........ 'nother ........ Level!

That's right, this is my recipe to take families to a "whole 'nother Level!" Just because we aren't software developers, don't know C++ or .NET, and pretend to but don't really understand those t-shirts with binary jokes or clocks that tell time in binary; doesn't mean we can't or don't need to create content that is as professional and foolproof as the wizards we've got in Revit already for things like walls. While I don't think we can expect to be able to create a custom GUI like the wall preview or wall structure editor dialog, I do think we can expect to create things as complicated and as reliable. But, to meet those expectations we need the things above, and probably some other things as well. Some that almost made the list are a Parameter Manager app/menu, Copy Parameter from/to nested/host families, the infamous Family Flexor (THANK YOU to someone who posted a link to a Type flexor add-in. If ONLY it did instances), and many more... Please add your own top 10 lists, or cue up the critics and lets knock some holes in the ones I've put down...
