As snap lines can only be created when the ruler is enabled, it would be nice to be able to enable/disable the ruler from the context menu, rather than going into the menu, similar to how grid has enable/disable grid in the context menu.
Was checking other presentation apps and Powerpoint and WPS Presentation include the ruler in the main context menu and i think that might be better.

Changed 'Display Ruler' to 'View Ruler' so that it follows the same menu path (i.e. View > Ruler).
