I don't really understand the linux clipboard/s scheme. Instead of understanding it, is there a way to simplify it into one, unified clipboard? You know, so I could copy in any app and paste in any other?
The current issue that's bugging me is IntelliJ's "copy path" action seems to copy the path of the current file, but I can only paste it back into IntelliJ itself - if I try to paste it into a terminal, the content simply isn't in the clipboard.
