It would be great to have a separate program for the purpose of programming or controlling the roast. In the program you can designate P,D,F based on time, temperature or a roast milestone such as YT, FCs, FCe. You could design your roast profile and then run the roast using this program to control it. Having this program would be a great addition to RT2. Right now there is just Playback which relies on manual inputs from a prior roast and lacks the precise input and editing capabilities needed to control and tweak a roast profile.
