Initial page with no tab selected

[gb]

Hi!
I am new here, I am just test driving the IDE editor and playing around with a demo app to see if Monaca is suitable for my project.
I have a bottom tabbar with a few items as the sole navigation, and I would like to start with an intro page and no tabbar item selected. The intro screen will be a invitation to use the app, it has no point to be seen again by the user.
How can I achieve this?
Thanks in advance!
