BeeDocs 3D Timeline on sale

the usual yaddayadda: I am not affiliated with or even a customer of (although considering becoming one) but I have seen this piece of software been discussed on this list so perhaps it is an interesting piece of information that it is currently on sale:

Although I am interested, I am somewhat appaled by the fact that the first thing I tried (displaying my due todo items in Things on a timeline) did not work. Empty window, empty selection box, empty timeline.
If I am doing anything wrong, the user interface is maybe not so intuitive, but I suspect it is just a plain bug. Still, your mileage may vary.
