So, by default, we ship a relatively sane amount of applications. But I frequently see people who advise people to "just uninstall all the defaults" or install using the minimal install, but in reality, if they could just flip a switch to install e.g. Firefox instead of Falkon and VLC instead of SMPlayer, we'd have happy users.
With Calamares, this is actually super easy to do. We just need someone who is good at UX design (@redwolf?) to design the screen, and I can implement it.
I really think this should supersede https://phab.lubuntu.me/T30 as well.
