The modern theme editor, released summer 2026, is far superior to the legacy theme editor in many ways.
-
Real WYSIWYG theme editing like in a presentation software
-
Better PDF export
-
Better slide rendering
We strongly encourage you to move your themes to the modern editor. To get an impression how easy it is to use the new editor, check out the tutorial video here.
Legacy themes will continue to be supported for at least until summer 2027, so there is no rush to migrate. But you’ll enjoy the new features, we promise! 😉
How to migrate
Unfortunately, there’s no automatic process to convert legacy themes to modern themes. The technology is just too different.
Please follow the tutorial video to create a new modern theme based on your legacy theme. It will not take you more than 20 minutes to future proof your themes!
