Some time ago some lovely person on the inkscape channel suggested the following fix to my desire to have inkscape default to landscape, full screen when I create a new document. It's become such second nature to me now I don't even think about.
But as I passed this tip on to someone today - it occurred to me it might be worth a wee blog post. Hope someone else out there finds this useful :)
Note: Make a copy of default.svg before embarking on this jiggery pokery - in case reverting to factory settings is required.
