GOverlay, the open source Linux application which currently works to help you really easily configure MangoHud (more on that here) has progressed quickly since the initial release.
With today's 0.2 release the developer, Benjamim Góis, is calling it a "Beta" as they feel it has come along enough for more people to try it out. Lots of enhancements have been made too including a quick check-all button to turn all options on, an initial implementation of a HUD preview, an explanation of the Vsync options when you hover, a notification when the config is saved and more.
Having MangoHud was quite a bonus by itself for having a really nice looking and configurable overlay with benchmarking abilities, but now having this GOverlay to super easily adjust how it looks just makes everything so much nicer. Once GOverlay can work with others, it's going to be even more awesome.
If you want to see the initial release in action, we have a video in our previous article. It works the same now of course, only there's a few more options and it works a bit better overall.
You can find GOverlay on GitHub.
