Brainstorm

In a number of applications you can bring up a popup menu by holding down on e.g. a link (like a normal right click menu).   The problem as I see it is that these menus are currently setup for left handed users as the menu appears to the right of the point held down so a right handed users hand will obscure the menu.   It would be great it these menus appeared (where screen space allows) to the left of the held point.   Ideally a configuration option would allow left-handed users to retain the current behaviour.
