Hey there,
browsing through the extension section I wondered which of those extensions are valid/make sense for me - not content-wise but in terms of framework version.
One Example:
ArrayDataProvider included in the framework since 1.1.4, but also a great extension for former versions.
Suggestion:
Extension owners can check compatibility for yii versions: compatible | not compatible | replaced/included | untested
Users are able to filter according to their framework version.
Just an idea.
Wish you a great weekend
Steffen
