READ DESCRIPTION FIRST!!!

Using a tablet? Ever miss the long gone brightness slider? Want to know the battery status at a glance?

This mini app resides in system tray showing battery percentage and charging status, and with one click, you are free to slide your brightness. Touch friendly and dpi aware. Right click to access additional ui settings.

IMPORTANT NOTE:

TRY before buying and leaving not working comment. I set the longest trial period so that you can test it. I don’t have the magic to make an incompatible hardware just work.

Brightness setting function works with most tablets and laptops, but not with desktop monitors (even the ones with DDC/CI, at least not for now). The app uses deviceIoControl to change the brightness just as the system does, if you care for the detail.
How to check quickly? If you change brightness in the native system setting app, you are probably good to go.
