Hello HN,<p>This was my on-and-off side project for a good part of this year. It's a small 3 in 1 Windows utility that I've released on the Microsoft Store. The app is a fullscreen modes manager, wallpaper manager, and a custom menu builder.<p>This started as a personal use thing and was initially just a tray icon that I could click to set my secondary monitor fully black for when not in use/darkness/savings, or fully white for when I needed some immediate illumination (lumo means light in Esperanto).
Eventually it expanded in scope a bit as I kept building to learn some more about Windows development and C# and added a few other features that I wanted up to the point I believe it may actually be useful for more people.<p>And although I know that closed source Windows apps don't usually get much love or traction here, I still value any eventual feedback or criticism from any potential users.<p>For the more technically curious, this is a C# WPF app using the latest .NET (7). I opted against MS latest UI tech (winui3) since unfortunately it's still not supported by visual studio's own visual editor for some reason. It's also pretty new and documentation/libraries are much harder to find than for winforms or wpf. Hopefully things will get better and I'll migrate eventually.<p>Note that this has only recently been published to the public and was mostly tested internally by some friends and me using my own dual monitor system and virtualbox (best multi-monitor emulation afaik) so there will probably be bugs. I've been using it daily for some time now though and it's been running just fine with only minor issues that I have been fixing as I find them.<p>I'm currently working on getting some better copy and demos for the website, as it is now essentially just some screenshots and feature description. Still any feedback is welcome.<p>Cheers everybody, merry christmas.
