@Alkaris@meow.social What do you need it for, specifically? In KDE for example, to browse files there's already an "open as administrator" context menu option when a folder is not owned by the user, and all apps I know that require admin permissions (e.g. KDE partition manager, kdiskmark for some partitions, rustdesk when enabling or disabling the service, steam when setting up VR the first time, etc.) pops up a password dialog for admin access. For some other things (like access to a serial port), people shouldn't use sudo, but should add themselves to the appropriate group (uucp in the case of serial ports). That should probably be a feature of applications like Arduino IDE (to ask for admin access to add yourself to the group). Just running stuff as root can be problematic, not just because of security issues, but also because of littering the home directory with files that the user can't read.
