Hi @kitchendoorspecialist ,
Thank you for trying out Buttonizer 🙂
You're right, when you have only one button it's beeing converted to 'single button', if you want to add more buttons you should click the button 'Convert to group'. From then you're able to add more buttons.
We're currently reviewing this behaviour for the next release of Buttonizer in April. Probably we'll change it to something more obvious!
If you have any idea's or suggestions about this feature, let me know 🙂
