It's okay, no one does (unless you're a programmer).
To this day, I still don't understand why there's no dedicated download button. It's up to the developer to provide it, and far too many of them are too forgetful/lazy to do so cause they expect you to just know how to compile it yourself.
There is a "Releases" section which provides downloads - however for that to appear, the developer has to either setup automatic building, or manually upload something as a release.
This is because by default, GitHub doesn't know how to build random projects out there - someone has to tell it how, and GitHub needs to be told that something is ready for "release".
I find this funny because I learned how to compile programs before I learned any actual programming because of Linux having a lot of the same stuff going on back in the 90s. Want this program? Here's the source code!
From a users point of view, I understand your concerns. When other clients are undergoing significant development. Itโs a little disconcerting to see the pace of Liftoff development slow and bugs not getting fixed.
