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.
Electron apps (more like erection apps), I rather burn my computer quit civilization and live on a deserted island than using any apps that has electron as a dependency.
