Feature: Reset Position

[PtrckM]

There are times I cant find where is the current position when using multiple monitors. It is a good feature to have a settings to reset the position to the default.

Yes, it is possible that the visualizer can end up offscreen if there are changes to the resolution or number of displays attached. There are some internal heuristics to help recover but they are not always good enough. Contributions are welcome, whether a reset button or improvements to the offscreen detection.
