The Metro Page Transition was updated, bringing a new feature:
Each page can now show a transition from right to left and from left to right (as well as top to bottom and bottom to top, if you have the enhanced version) without needing to duplicate pages to achieve this effect.
Until now, you needed to duplicate the page, using one copy for each desired setting, and jumping to the instance with the desired effect. Although each page can usually have only a single setting for a transition, the Metro page transition now can be overridden via one line of Lua code at runtime, and no page duplication is required when designing the project. This makes things much easier to maintain.
Clicking the image below will take you to a demo project:
The right/left transition is free, and if you want the up/down transition as well as other features, you can get the Enhanced Version by making a donation.
The Metro page transition is part of the "Utilities for AutoPlay Media Studio 8" package.
