Well, first of all a drag and drop feature did exist in Aware where you could drag/drop "things" between different panels (queries for example) but that feature got removed somewhere in V7 I think it was. It was replaced by a better version of reordering "things" inside the one query (something I don't think is working now either by the way. I can't remember the details but I tried to get it working in V7 and found various bugs i.e I couldn't use it). Support promised to the best of my recollection to bring the drag/drop between panels/queries etc. back but I don't think it has gotten reintroduced again. IMO the drag and drop between panels and reordering inside them should both be available in Aware (and possibly improved/modernized). If you look at most webapps today, they use these types of operations all over and not having them makes an app look like something from the 90's.
That said, when we don't have these operations etc. available, we can always tinker ourselves like I do (and others like John) but it requires some JS skills (and time quite frankly as you have to do your own solution and then integrate it in Aware). I can share a rudimentary sample BSV with the things I've done as soon as I have something more substantial but is a low priority on my list so might take a long while before that happens. If you are up for it, I would recommend you to take a stab at integrating something like nestable yourself (see my link + google nestable sample code) or any other drag and drop JS code/plugin. The upside to doing it yourself is you learn how "easy" it is to integrate whatever in Aware.
