On Page Load Action

I’m building a new app in Pages and really enjoying some of the Pages-specific features. One additional feature that would be awesome would be a custom “On Page Load” action.

Here’s a simple use case example:

Select “Books” item from a list of types of resources. Go to “Books” tab. Upon loading, if only one book in collection, go to details page.

I realize that I could do this with custom actions, rollup column, and if/then on initial button press, but I wanted to give a really straightforward example.

I’d love this in Apps too…I’ve always wanted actions for Tabs. Default would be “non”, but I’d love there to be an action sometimes whenever a user clicks a tab or a tab is opened for the first time.
