Feature Request: On-Screen Display for Contrast Adjustments

[taufikinfj]

Hello,

First of all, thank you for creating Twinkle Tray. I use it frequently and it works great.

I would like to request a feature enhancement regarding monitor contrast controls. When adjusting brightness using keyboard shortcuts, Windows displays the standard brightness OSD/animation on screen, which provides useful visual feedback. However, when adjusting contrast through shortcuts, there is no similar on-screen indicator.

Would it be possible to add an optional OSD or overlay for contrast adjustments, similar to the brightness animation, showing the current contrast value when it is changed via a shortcut?

I think this would improve the user experience, especially for users who frequently adjust both brightness and contrast from the keyboard.

Thank you for your time and consideration.
