First of all, great idea. This is one of those things where it might be really helpful add-on but is the time saved really worth the extra code and the additional time spent updating the plugin and such. I know time updating plugins is fractional but that's also pretty much the same when it comes to switching pages the normal way. Also, what if there's a pluigin conflict or something. The time saved is lost figuring out the issue. My 2 cents.
