I hear ya I hear ya - I often forget that it's not in EDP as well, and hey I work here!
I can say that the reason we're not looking to add it to EDP is because we're working on moving forward with the technology behind QDP, and looking to replace EDP with full-page QDP technology.
What we are working diligently on is making QDP a more enjoyable option for all users that can finally replace EDP, which means that we're adding features and functionality there. I also hear you terry.ginzburg about the kind of interesting loops you can get into with QDP. That's something we're thinking about and looking to address as well as the full-page functionality that people want.
I know that's probably not what you're hoping for, but that's what we're trying to do. Hopefully one day we'll even be able to just type our @mention!
