"A press confirmation for the "power" remote"

totally agree with it.

I had just wrongly press the hibernate button to let my pc enter bootloop. I am now so nervous whenever I am on power menu.

"any little press can't be canceled"

that is true... I think it can be just done by handling the remote action by comparing the location of onTapEnd whether it is still on the button.

I am also so disappointed to found that these request were from 6 months ago but they are not implemented.
I hope the development team takes user experience more serious...
