***The speed slider has been removed entirely and the speed of movements starts small, and ramps up the longer the button is held down. This behaviour appears to be more user-friendly, but I would like to have feedback on how it is working.***
Review: The intention was good. However, I liked the previous speed control better. It seems more practical to me. Perhaps it would be interesting to leave both options available, to be chosen in the settings.
***The other big change is in how a PTZ device is associated with an OBS source. ***
Review: This is great! Excelent idea.
The speed slider has been added back in another form. In the settings dialog there is a per-camera setting on the maximum Pan/Tilt, Zoom and Focus speeds. You can use that to limit the maximum speed that a camera will move. I'm still working on improving the UI, but I hope that will be a functional first step.
