Popup menu's select all only selects visible area and not scrollback
The long press popup menu's "Select All" only selects visible area and not any of scrollback, making it almost impossible to just simply copy out the full output of a command on touch (where selecting that range manually instead is just really cumbersome and difficult to do). In all other terminal emulators I ever used, "Select all" will select the entire scrollback and not just the visible area, so I suggest that console should behave the same.
