Please expand Mouse sensitivity adjust ranges?

[juj]

Going in the Raspberry Pi Menu -> Preferences -> Keyboard and Mouse Settings, there are the following two fields:

Acceleration: the slider allows a value between 10 and 100.
Sensitivity: the slider allows a value between 10 and 100.

I dislike using the acceleration setting at all, when using the desktop I feel like my mouse cursor is always flying all over the screen where I did not intend to, so I'd like to set acceleration to absolute minimum. However 10 is the minimum setting, so it would be nice to have 0 as the minimum instead.

After doing that, I find the mouse sensitivity is not enough, so could the maximum value for the sensitivity be increased from e.g. 100 to 500 or similar, that should be well enough for everyone(?).
