Alternately, you can use the MoorMap plugin which is not only dynamically resizable but also positional and has some additional features like custom annotations, breadcrumbs, overlays, etc.

Unfortunately, due to a limitation of the Lua API, you have to click a button on the map to update your position manually but it can still be quite helpful...
