Is there any way to maximize an InfoWindow in Google Maps v3

The old (v2) version of Google Maps API allowed info开发者_JS百科windows to be maximized (see this example) but I can't find any equivalent feature in v3. The same happens with tabbed infowindows too (they aren't supported anymore).

Is there any way to do that (even with a plugin)?

By looking at the documentation, it looks like there's no way to perform maximization on InfoWindow.
