You can customize any aspect of it, from simple style changes, all the way up to fully custom transitions and interactions. We include three hours of customization for free, plus an additional hour per additional event day (so a 3 day event gets 5 hours of customization for free; 3 for the first day, and two more for days 2 and 3). We provide an estimate prior to doing the work, and anything over the free hours would be billed in addition.
In the end, you get a custom template and that template can be used for both Event Social Walls, and Social Media Digital Signage. We do not currently provide customizations for our Social Media Hub product.
