I've seen a couple users boggled by the fact the Itch app can install and run games, but hitting the "scan for games in installation folders" seems not to detect any games they've already downloaded prior to getting the app.
After a bit of testing, I think I've figured a way to get it done, but it's definitely not user-friendly. (and similarly cumbersome to making appimages show up on linux desktops, if that helps explain it.)
Since this is a feature that plenty of people seem to expect of the application (but since I don't plan on going out my way to request a new feature out of the blue), I'd just like the to launcher to add a label somewhere, specifying that this behavior isn't supported. Ideally on the results prompt for the "scan for games in installation folders" button.
My personal use case is that I live in a community which doesn't have permanent daily access to the internet, and I can only access a stable wifi connection sometimes, mainly when I'm away from home. So, being able to add games manually would be convenient. Nothing a bit of properly organizing game folders couldn't solve, but still, convenient.
