Hi @cohereandnow,
Thanks a lot for reaching out about our plugin! We’ll do our best to provide more details about it 
Regarding why you haven’t seen any plugin actions on the demo page, it’s because the Accessibility menu is set as a reusable group. Everything is configured there. You can take a look here at the reusable element and all the actions provided.
As for increasing the font size when the page width exceeds 800px, it’s quite simple. You can create a workflow that triggers when the page width exceeds the desired limit. However, we want to mention that the font increase and decrease are still valid even after refreshing the page. This means that if you refresh the page multiple times, the font will continue to increase/decrease more and more. To ensure that it only increases once, add another action to reset the font size to the default.
As you can see on this small test page we created, I’ve set up the workflow to trigger when the page width exceeds 800px and has two “Font size” actions. The first action resets any increases or decreases that are already applied to the page, while the second action increases the font size once.
Please let us know if you have any other questions or if you need us to clarify any points provided above!
Wishing you a happy holiday season 
Best regards
