Customize the interface for viewport management (lock symbol)

In AutoCAD, to lock the viewports in the layout, there is a lock symbol at the bottom of the screen. In DraftSight, instead, you need to select the viewport and open the properties window to lock/unlock the viewport. Is there a possibility to add the lock symbol at the bottom of the screen (where the buttons for activating the Esnap, etc., are located)? Furthermore, in AutoCAD, at the bottom of the screen, when you are inside a viewport, there is an option to exit the viewport and return to the paper space by clicking on a button (a sort of arrow). In DraftSight, however, you must double-click on a point outside the viewport. Is there a possibility to add a button similar to AutoCAD's?
