The layout of this tool is very easy, you can easily drag & drop elements in order build up an ideal looking content box with ease! We have been able use it as well within our own agency but I don't think there are any specific features we've used outside from using their free account which allows us access through them creating pages or ads without needing clients login details etc - just like how they do internally when managing accounts / customers data/ info (which makes sense).
There's nothing really negative about taplin other than if u're not familiar at all then its going take some time getting around what each element does so make sure someone who knows comes along side help out too :) Great platform great people behind making products good value compared prices elsewhere! Creating multiple boxes across different platforms has become much easier now thanks mainly due being connected via social media channels allowing me more.
