Please provide more usage information and sample code. The documentation is almost useless because it never tells me how to use the code.
Look at how Microsoft documents .NET. They provide substantial remarks informing us how to use the API. I never see this in any of your documentation so your controls are harder to use, and if they are harder to use... well, why am I using them?
Please provide remarks for each API that help us understand how to use it, and please put sample code in the docs directly.
This is true for all your documentation.
