Unfreeze Function? Customizable Default States?

I know there is a Freeze function that ignores input from the optical sensor (or disables the sensor, as the case may be) while a button is pressed and a Toggle function that will do the same once a button has been pressed until it is pressed again, but I would actually benefit from an Unfreeze function, so that I need to be holding the button down in order to use the function while Toggle is in the off position. I tried using the Freeze button thinking it might work vs Toggle the way Shift does vs CapsLock, but that did not work. My use case would be for mousing arrow key presses, where having the feature always on is a pain and a toggle will work, but Unfreeze could allow better precision. I can see where such a function could be equally useful for mouse motion. Is this something that is on the roadmap or has been previously requested?

If the aforementioned feature were built, it would also be useful to be able to program the default state of each sensor so that Toggle wasn't needed after each re-plug and/or update, but it isn't too big of a deal to manually Toggle each time those events occur. Regardless, I'd also like to know if this is on the roadmap or has been requested.

Finally, while typing all of that, it occurred to me that it would also be nice to be able to program the default "Mouse Speed" (formerly "DPI"?) for each side. So, is that a roadmap or requested item?
