	=== Clipboard ===		=== Clipboard ===
	Due to the security concerns, Wayland defaults to the ~~behaviour~~ where only the focused client (window) can set the clipboard. Clipboard ownership is tied tightly to the focused client so that a background application cannot replace the clipboard contents. The intention from Wayland protocols is to improve security. But that can be an issue if you are either using a clipboard manager or perform rapid copy pasting in the terminal (like using macros in vi).
