Hello, I am looking for a platform where I can easily create custom themes in little time. I read a recommendation about this product and it looks great from the video; however, I also read that if you play with widgets you lose all your work so you can't change widgets later - he made it sound like a dealbreaker. I'm wondering if you guys have any updates on this?

It isn't clear what you mean by "play with widgets" and "change widgets later". Can you post a link to the thread you read that in?
