It would be also great to have a function to insert an extarnal webpage under menu button as wrapper (I don't know if this is the right word in english).
Now in 6.1.4 you can bulid a custom HTML which is great. This would be an option to open an external webpage under one of the main menu buttons. The header of Dolphin (with menus) stays the same, just the content below that changes to whatever you want.
