What is this Dash? Is it only on the SVN, as WAU isn't picking it up. I'd like to give it a try
I assume they are talking about http://www.wowinterface.com/downloads/info7391-Dash.html. I haven't given it a shot yet but I remember someone on the EJ forums posting about making a "Dock" style addon where you could park things that you dont use often but still want to have semi-visible or easily accessible. It had nifty mouse-over animation popouts and everything. Dash sounds like the same sort of idea, you park stuff you don't want to see often on the layer and then use a keybind to toggle viewing those frames. Addons like this will help clean up a lot of clutter.
