Static Pages duplication

Hello,
I have made a plugin to allow to duplicate content (blocks/properties and content) from a static page to another. If there is a multi-site, then one need to create the page in all sites and then copy the contents from src to dst page.

What I don’t know is if the way that I implemented the feature is the correct/best one so I have the following questions:

1) How can I add a button to the static pages toolbar (side by side with the save button)?
I know I can duplicate the file in my plugin/theme or append the button via JavaScript but I’m looking for some hook/event so my plugin does not break/ get broken with future RainLab.Pages updates. Check image bellow.

2) Is there a easy way to create a static page by code “new …\Pages\Classes\Page()” maintaining the correct function of the Pages plugin?

3) Can I rename the name of the file (blabla.htm) from php code of an existing static page?

I hope someone have some insights about this because I really could’t find anyting about this in my searches.

Best regards,
Domingos
