This open source app made by me in Electron is YouTube client for Windows. I'm also working on such client for Linux/macOS.
If you want to download and use this app, go to releases and download Setup.exe, because I couldn't upload all project files via Code section in this repository (because of files size limitations)
P.S.: Don't worry, you can login in this app with your Google account, because it's based on original YouTube website. I can't see your passwords and even emails)))
