So, quite fond of the map function, but there's a couple of things that bug me.
a) It has to be a square. Why? I take it there's a good reason for this, but it seems incredibly arbitrary.
b) The level of zoom - it almost might as well not be there. There's 3 levels, and 1 of them just ends up showing a grey box around your map. The actual effect of this is, that if you happen to type out/link something/place a table of some size in the "info" section of the map markers, it'll innevitably zoom out into a gray part of the map rather than keep it nice and centered.
In fact, the most grevious thing in my mind is probably the latter part. I just don't see a good reason to have a zoom function rather than a nice centered map function if only 2 of the levels of zoom actually do anything.
