Rodrigo Rocco at Jomres Plugins has been working on Jomres for over a decade. He has lots of useful plugins, including the wonderful Valentina template override.
If you're considering Jomres for your project, then I highly recommend you check out his demo site to see what can be done with some of the excellent code he's created.
Note : Rodrigo's plugins are not part of the Jomres core package, you would need to pay extra for his plugins via his website.
