Still working on my app launcher. Currently working on on user config. Recently I added support for app icons and there freedesktop.org icon themes. Icon themes are more complicated than I expected. Themes can have multiple fallbacks themes which themselves can have multiple fallback themes. Totally makes sense. I just did not think about it too much before implementing it. Allowed me to implement a nice breadth-first search. Most themes have a single fallback theme, so it is not of much use, but hey, I follow the spec. 😅
