DevToys VS MicaForEveryone

https://devtoys.app/ Windows only though.

Strictly speaking, DevToys isn't an online builder.

Here's a few: - MVVM Toolkit sample app - Ambie - Brainf*ck# - DevToys

Also recently came across DevToys which has a lot of handy tools in a clean interface

Check out https://github.com/veler/DevToys

If it helps, here's also a bunch of open source MVVM apps you can look at for inspiration (again, they're UWP, but if you ignore the XAML differences all the rest is just plain MVVM): - https://github.com/jenius-apps/ambie - https://github.com/Sergio0694/Brainf_ckSharp - https://github.com/veler/DevToys

Replacement for tools like devutils.com and devtoys.app

Download MicaForEveryone

There's no system setting, but you could try this: https://github.com/MicaForEveryone/MicaForEveryone

3)Install MicaForEveryone its a solution to make title bars dark (but it can do more)

Tools used | StartAllBack, OldNewExplorer, - MicaForEveryone, TClock Redux

You can do a fair bit with Stardock WindowFX and Mica for Everyone

Probably using MicaForEveryone.

I used an app called "MicaForEveryone", it's a title bar backdrop utility to change its title bar style with options like Acrylic, Mica, and Tabbed. It works on Windows 11 22H2, you should try that. https://github.com/MicaForEveryone/MicaForEveryone

Are you sure?, I took the image here, and as you can see user x-0D is using Windows 11 in the dev channel, and created the same issue in the Rectify11 repository. Maybe some previous build of rectify had this feature.
