Option to deactivate the global grid on specific pages

Depending on the layout, the global grid will have unnecessary buttons for certain pages, keyboard pages in particular. Therefore this request.

Additionally, but that would only be a top-of-the-cake thing :) : Option to have more than one global grid. So there'd be one global grid for the pictogram pages and one global grid for the keyboard pages, for example.
