Click a LDB plugin to drop the cheapest thing in your bags. (The cheapest grey item, by default...) Also adds a "sell all" button to the merchant frame. Yes, this is just like FuBar/Broker_GarbageFu. It has all the crap I didn't use stripped out, though. So it's 90kb with libs, instead of GarbageFu's 300kb. I'm such a size queen. (I was just going to fix an issue I was having with GarbageFu, and was horrified by the code. So I wrote this.)
You may have asked yourself... "does my alt know that?" Well, this will tell you that via the tooltip for a recipe. It won't know what your alts know until you populate the data by opening your trade skills on your alts, without any filters enabled.
