It could be very cool idea to add that feature like on smart TV Remotes, by holding finger on the screen and moving the mouse by moving the phone.
Unfortunately the Kodi API is bugged for mouse control. Only 4 directions would like a lot the function
Too bad, but it would be pretty cool, then we could all replace our kinda’ “locked” Smart TV’s with more powerful features on our PC’s
For now I am using another app that uses my phone as a touchpad
I hope Kodi will include more features for flexibility when Leia gets out of beta
