I am working on compiling a set of code snippets for CC but these are very limited in scope. There will still be a demand for commercial plugins/extensions that provide much more complex functionality. This is a good opportunity for developers in our community to step in and fill that need (and generate some income for themselves).
It might be worth compiling a list of the paid plugins we are currently using with WooCommerce, so that developers can start considering which ones they might like to take on.
Mod edit: split the question off to a new thread: Ethics/legalities of forking a commercial plugin
