We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
People that argue over Gnome vs. KDE. Shut up and use whatever you like. No need to yuck other people’s yum.
