@ghutchis Do you think that with the 1.99 release it’s time to set avogadro.cc to redirect to two.avogadro.cc?
It still feels like half your time on the forum is spent replying to support requests to say they should upgrade 
The latest being #5284, but also 5254, 5217, 5114, 5079, 5067, and that’s just in the last three months…
With all your recent work 1.99 is now pretty much on par feature-wise with 1.2, the only things absent really are the nicer interfaces for orbitals and live optimization, but both are at least possible to get in 1.99. And it is far more stable and less buggy.
