I wish this was available earlier, would have been a great help to learn MTEX. :)
Few points,
1. Warning about deprecated command, does not affect the plot though.
Warning: Starting with MTEX 5.1 "ipdfHSVOrientationMapping" has
been replaced by "ipfHSVKey".
2. The script recorder is capturing every change, perhaps recording the last state could be an option? Example: say in T2 I am plotting grains map and code with all the grain parameters I have tried is getting in the script. But I only need the final plot to be in the script to refine/modify in MTEX. I propose to keep two option in T0 beside "Record Script" button - (1) Record all events (just like now), and (2) Record only last tab state.
