Hey - first, thanks for making this. I had a couple of those servos sitting around and the GUI tool is really helpful to get it tested quickly. The wiki zip files are not great to use for that.
I was thinking of adding a full register dump tab to the UI - would you be interested in a pull request ?
I also wanted to note that there's also recently officially released python package and a github repo. But i'm not sure if WS / FT are fully compatible.
