I love the idea simplify automate wireframe for designer. It helps the designer to sketch their first idea and will elaborate by the time goes on.
As product manager, usually I find the hardship to prototyping my problem and idea into wireframe. I spend a lot of time only to draw it simply.
I do believe, with wireframe designer it will reduce unnecessary time. Just can't wait to know the next improvement :)
Goodluck !
