Bottles isn't exactly a new Linux application but it's one I had only heard about recently. It's been advancing a lot in the last year and it's really looking great. Unlike other manager applications including Lutris, GameHub and so on it has a singular purpose — Bottles is designed to give you the best possible experience when managing the Windows compatibility layer Wine.
It includes a lot of options to allow you to easily tweak your installs with a few clicks of a button, which is exactly what I love about it. There's a few "runners" included which are various versions of Wine like their own Vaniglia, that has a few wine-staging patches and a newer updated theme and Lutris' Wine.
Everything is run inside Bottles, contained areas that keeps all your installs separated. A form of sandboxing from the rest of your system, and if you go with the Flatpak package you get this in full. A benefit of all this, is that each Bottle can have multiple restore points. So if you messed with it and it broke your Windows game, you can send it back to a previous point when it worked.
Much like the Winetricks app, Bottles also includes its own dependency manager allowing you to install extras into your environments. Some games and applications will only work with these extras, so to see it all included together - again with only a few button clicks is wonderful.
Bottles might have one of the smoothest and best looking ways to install and manage games / applications with Wine on Linux. Give it a try.
