Lawnchair is a fork of the original pixel launcher that gives some quality of life upgrades to an already good piece of software, like being able to remove the search bar, resizable / reshapable icons and fonts usw. Its also open source, so feel free to check out the github.
There is no app store release right now but they are working on it. I've used the alpha versions for two years now and it has worked fine so far.
I hope so. I've been using Linux for 10 years for everything except gaming. And two years ago i went fulltime with proton and lutris (switched to heroic though).
And let me tell you, we're at a point where its multiple times more straight forward to just install something like Fedora KDE, and do almost anything windows can, than trying to deal with whatever the hell microsoft is up to these days.
The biggest problem still is software discoverability. It is our duty to guide newcomers where they want to go instead of gatekeeping.
