1. Knowledge sort still works -- it's currently just hard to see the radio buttons being selected (as reported by 2 different users already)
2. The track button only shows when hovering the window, I can't recall if there is a cancel button (can use waypoint window alternatively).
3. The Default Options when has ways to save presets. Load/Save buttons.
You can create your own presets. With this + default performance dropdown in settings, there's no good reason for me to make generic presets really
