As the title says... Need a mouse with htpc controls..
Mainly volume buttons, play/pause, mute..
So four customizable buttons at least
Yup already have it installed on my mobile..Try *play.google.com/store/apps/details?id=com.Relmtech.Remote&hl=en
Get its PC side application here

And then decide if its worth spending 4k+ for a wireless mouse with media controls.
