I can't agree you more.
The tools are designed for the mechanics. There are so many problems you will encounter in your workshop, though we are trying to simulate them, there are still a lot more we can't imagine.
I can't gurantee we can do a flawless work, but we are listening. If we can't satisfy you, it is not because we are not hard enough, maybe it is beyond our reach.
I have asked our engineers to put a release note for every update program, so you will know what is inside.
The idea of purchasing the vehicle programs independently is proposed at the first beginning, but it is too complicated so we finally let go this idea. Later when we are stronger, we will provide more options for our customers.
Right now, I would ask our users to be more patient.
