Impressive, but be very careful going up against established players such as Balsamiq because you will have a difficult time competing. I am not sure if you want to one day make this a paid app, but if you do, think about developing and marketing it to the needs of a specific niche. Remember, there are thousands of similar "projects" and clones of existing software that died a very slow and painful death because they were not profitable enough to continue developing.
Thanks for taking the time to play with Mocktails. You are correct in that it's difficult to compete in this space. As of now, we are thinking of having our marketing emphasize our strengths such as publishing and built in version control.
To be quite fair though, the day where we have to worry about marketing is quite far away. For now, we just have to buckle down and keep building the product.
