Why is "Memory PLUS" a menu bar application?

Memory PLUS is designed to be a menu bar application as it helps keep the application running in the background, while being easily available for you to monitor the current memory parameters on your system and/or trigger the automatic or manual cleaning on hitting low free memory conditions. While a popover is displayed with the current memory parameters on left-click, a right-click on the menubar brings up a context-menu with useful options. An application preferences window is also available to be launched from either the popover or the context-menu.
