Add the option to turn off mouse acceleration. I think I would fins it much easier to aim the pointer if I could disable it. I always disable it on computers. You can just add it next to the pointer speed setting under General > System > Additional Settings > Pointer Options
Two other settings I think would make sense to have would be a setting to disable the shake-remote-to-show-pointer feature. Although I like it I can sometimes find it annoying, so why not let the users decide. I always hate it when there aren't settings for things like these.
The other setting would be to disable the pointer completely as many users have written that they want to disable it.
