The GUI stuff is on my list of things to do but I've been especially busy lately, and was gone a lot over the holidays. I had hoped to get a release out by the end of last year, but obviously that didn't happen.
Part of the reason it's taking so long is that it's not a simple quick fix; the reason being that in order to do some things required the widgets will have to have access to the data in other widgets (which the GUI system currently does not yet provide a mechanism for). I'm getting to it though, thanks for reminding me...
