Hi,
I am sorry for the inconvenience caused. I would like to offer you a premium license if you would like to test it.
i) We will be adding the Canvas option.
ii) For the documentation, we did find that 3 docs were missing.
We have made sure to fill them.
At the same time our website and docs are being further improved.
We are working on a lot of Video tutorials and will soon be launching them.
They will be added to our docs.
iii) If you will help us replicate the issue, we will issue a fix ASAP. Also we would be happy to offer you an additional year of premium license if you would show us.
Regards
