I just PAID again for #PIDToolbox Pro. And it is such a shit software. I mean what it does is genius, but the user interface and every interaction with it is terrible. You have to install Java and the Matlab Runtime (>2.5GB!). It does not integrate well into the Mac ecosystem at all, and I guess Windows is a similar experience...

I'd actually PAY a monthly fee for a nice #PID #tuning web service. #FPV
