[Feature request]: On-screen Mouse Wheel

[Gfrni]

The problem
In many games and apps, mouse wheel is needed, and there's no good on-screen input method to emulate mouse wheel events.

The solution
In On-screen Controls Setttings, add a check box named "Show mouse wheel up/down buttons" to emulate mouse wheel on touch screen, if enabled. Two buttons need to be added. Similar to the currently supported on-screen gamepad buttons.

Alternatively,
you can add an option to emulate mouse up/down events using the physical volume up/down keys

You can scroll using two fingers, like on a track pad.

Thanks. I didn't know.
Though it didn't help. Because such an input method for mouse wheel, results in unwanted mouse right/left clicks. It is totally unusable in a game or app that clicking accidentally, makes trouble.
So, I guess users may prefer a pair of buttons for mouse wheel up and down.

Another suggestion, related to this issue:
Phones (the most of moonlight-android users, maybe?) have a wider screen than desktops, so users have two unused blank area in the left and right sides of the screen (and showing the desktop screen (which is not wide) in the middle). Why not always fill that blank part with some buttons (e.g. mouse wheel) or any other necessary stuff?
