It's user friendly and I'm figuring it out as I go... just a bit of support with downloading to my google drive and figuring out why/when to use the link would be great.
2021-05-20
It includes everything I needed to do, and then some. Its much more user friendly then even Adobe itself. But, for the price, and my specific needs, it works great.
