This was a outstanding presentation on software design.

And my question could probably not be better timed: where can I see all available form properties for form API?

What if we could look up all the different properties on Then use tagging to easier find the property you need.

I recently found out that #cache is new to Drupal 6(fapi3).
So: #cache is a boolean value (true/false) that caches the value that are being submitted. Tags: store, cache, save.
