Thanks for this. "The Missing Usage Examples" wouldn't have been too brazen, and definitely not inaccurate.
Demos and examples are severely lacking and have been since initial launch. Unfortunately I rarely find myself motivated to improve them when there's so much fun feature coding to be done...
If you (or anyone else reading this) is interested in helping add demos for the website, I eagerly welcome it. The current demos are in GitHub at https://github.com/lojjic/PIE/tree/master/demos
-- you can just fork the repo, add your demos, and issue a pull request for it. Then I can pull it into the main tree and add it to the website.
Some basic guidelines: demos should follow the same basic format as the current Tabs demo -- brief explanation of the demo, a screenshot plus the code in action, and the code itself (preferably with inline comments explaining parts of the code that need it). I like demos that combine multiple features to implement common use cases (like the tabs); but there's also a need for feature-by-feature demos, like the PNG transparency demo from this forum topic, or one that shows all the different border-radius shorthand syntax aspects. The test cases in https://github.com/lojjic/PIE/tree/master/tests
might be a good starting point for some of these feature-specific demos.
