Nice project. And thank you to make a GNU/Linux version ! ^_^ That's great ! ^_^
By the way, I have a problem with it : it's impossible to load a world.
I have download the AppImage file (Valheim_Map_Viewer-x86_64.AppImage), made it executable and launched the App. To that point, all works fine. But when I click on the "Load World" button, nothing happens. The button blink (if I can say like that) but nothing else.
I hope it can be fixed. ^_^
