I find it really easy to use.
You can customize the process very easy.
You can also communicate with people ad they don't even need to have the tool. They can see the processes on the internet which makes it easy to collaborate with people that don't actually choose to use the tool.
It's easy to use generally, due to the fact that it's really basic.
It has also a lot of Planteria, I know how to paint in it, however, you can use different samples, depending on the structures that you want to draw. It has a lot of possiblities.
