Hey @Chris_D !
Hope you're enjoying the updates latetly (and of course the new redesign of our editor which is in beta) 🙂
Thanks for bringing line-breaks for labels to our attention! Since we're currently working on the new version of our editor, I think line-breaks would be a great addition. We've added it to our list to work on!
That means as soon as our editor comes out of beta, Buttonizer will support line breaking in labels! We hope to finish the editors redesign in about two weeks.
Let me know if you have any further questions and what you think of the redesign! I'll update you as soon it has become available 🙂
