@codesardine, me and @Ste74 have been working on the hybrid installation with calamares. The hybrid is between netinstall and iso decompression. The goal is that you could install offline like usually, but if you have internet connection, you could choose between different browsers, office suites, and other extra software. This would also make it also easy to choose if you want snap/flatpak/AUR support. It also allows keeping the iso size smaller and having an updated the system after the installation.
This could combine the best features about calamares and manjaro-architect, if we get it working like we hope.
