Page Editor
The Page Editor allows you to update the page that is ready to play. When you create a page you can fill in the info based off of the Porta Template.
See more of the Porta Template Builder.
Once you create a template you can view the Page Editor by selecting a page from a playlist.
If you close the page editor you can reopen it by going to Window > Page Editor to reopen the Page Editor. It will be blank but selecting a page will fill in the data.
