This simple mod will add Youtube to the n97's video menu as seen below.

Of course, it requires a hacked N97 !

And upon selecting Youtube icon shows and info, click again and it will launch the Youtube app.

How to? Simply, Install Youtube and then paste vcns_matrix_items.xml into C:/private/101f4cd2/suites/tvvideosuite and reboot your device.

Ps : Any installed application can be added to the video menu list by changing the uid in the plugin file below.
