Hey wassup ya'll
The first ATC program I downloaded was Pro Controller.
I got that running but didn't know how to use it.
In my opinion it was a bit complicated, and you had to memorize allot of keyboard shortcuts to complete some simple actions.
When I got IvAc, and read the manual and got it running, I knew exactly what was what, and what to do. It's true that it might be a bit complicated to new users, but at the same time it makes the program a lot more user friendly.
Taking in consideration that this first release is also still a test version, with the new release I think they might have done a grate job providing the flight sim community with another great ATC program.
Regards,
