GS should steel someone from Nemetschek. VectorWorks has had this for years.
Even without an exchangeable format, it's inexcusable that AC cannot remember your settings after a relaunch. Palettes are closed, certain preferences are reset, the maximize button doesn't even work right, at least on Mac. This is basic stuff. They should be embarrassed.
