I think this is a good tool, but I am not sure. Looking at it with a default aircraft, it looks good. But, it does not work with PMDG aircraft, and that is all I fly. So, if you fly a third-party high-end aircraft, you may want to check with the vendor before purchase. The description does not list aircraft for which the tool has not been confirmed to work.
If possible, please add a feature to make profiles for specific aircrafts. When I fly the Fenix A320, the Offset and Stop Offset is different from the normal A320.
