	~~For now, the SmartScope software contains a basic set of measurements~~. ~~This number of measurements will grow~~, and ~~together with it,~~ the ~~way of dealing with measurements will change.~~ Measurements ~~can relate to a channel (eg amplitude or mean voltage) or to the system (eg update rate).~~		The Measurements subsystem has been significantly expanded since v0.13, and therefore they are covered in the dedicated [Measurements] section.
	~~Measurement boxes can be shown or hidden by tapping on their corresponding button in the bottom-right corner. They can also be removed by dragging them out of the grid area~~.
