Do you happen to know what (if any?) technical advantages appimage has over “portable” applications (i.e. when the app is distributed as a zipped directory containing the executable, libraries, and all other resources)"? As far as I understand, appimage creates an overlay filesystem that replaces/adds your system libraries with the libraries that the packaged app needs? But why would that be necessary if you can just put them in a folder along with the executable and override LD_LIBRARY_PATH?
