If it is just a syntax modification in the drivers I will rewrite them, bit by bit, if I have time onsite.
If you Update the GUI it would be nice if we can talk before, so we can add some, in my opinion, neccesary features. I would pay for an update of our 4 license, and would buy some more, so you should offer old GUI users an Update Plan 😉
I am realy exited how the update will be!!
