Meanwhile, this was a feature on KDE-land since Klipper, which goes back (as far as I know and if I remember well) to KDE 3 or sooner.
There have been third party clipboard managers forever in windows, which is kind of funny because that is almost more like the unix philosophy than expecting the UI system to handle it all.
Klipper was entirely a different program, process, etc. that was using the system tray. Nowadays it seems to be a plasmoid in the system tray. How can that be less of a UNIX philosophy than the Windows alternative? Because it’s developed by the same community that makes the shell? That doesn’t make sense to me.
To be fair it may be a security concern if someone is copy pasting passwords
