Center map around several points

Is there a way to center the map around several points? I've got 2 locations, as you can see here: and it's centered on the one, pushing the other to the very edge. It would be super handy if we could make it center over both, or, keep the same view as in the map editor, the same way it keeps the zoom level.

Would also be nice if we could add custom (or there were some built-in custom) markers and such. Like so many plugins around here, this one's almost there, but could just use a little more work and finessing to make it a really great plugin.
