Just had a go with Padlet's new function: Sandbox. It's very impressive. It's not just a good substitute for Google Jamboard (though Google Jamboard is free); the Sandbox function can also do several other cool things, like creating an interactive, clickable presentation (somewhat like Genial.ly, and Thinglink).
So, after I've become a proficient Sandbox user, I may not miss Google Jamboard any more!
