Please consider adding UI or keyboard brightness presets for Windows Store users

[k3davis]

This is a useful bit of software. Thanks for building and maintaining it!

For my use I often set one of my monitors (secondary) to minimal brightness, and my primary monitor to something like 20%, for when I'm using my computer at night. I would love to be able to switch between these two "modes" like presets - eg. one preset for full brightness, another for this saved reduced brightness.

From #324 it looks like I could achieve this via the command line, but I'd prefer to use the windows store version to keep things up to date automatically. I'd be fine with a hotkey combination or a minimal "presets" UI like from the right-click context menu on the tray icon, perhaps.

Something like this may also address #796 which would allow easy reset to full brightness.

Finally, have you considered getting this application added to Windows PowerToys? microsoft/PowerToys#34521
