Simon, I would provide a time frame for you if I had some confidence in it. The design for all intents and purposes has been ready to be integrated with Couch for over a year. For better or worse, this simply hasn't been prioritized. Most of the remaining work that needs to be done is out of my hands.
Hello @cheesypoof,
If the new panel is made on jQuery I suppose it would be nice to add smth like http://odyniec.net/projects/imgareaselect/ in it. There are many working solutions GD+imgAreaSelect so I think it would be not too difficult to implement.
Now cms:thumbnail tag has fixed width\height, and I think the best solution that will have compatibility with previous versions would be adding "use_dynamic_crop='1'", so the button in Admin Panel will appear. By pressing it a Modal window is displayed with imgAreaSelect.
Any chance to get this feature implemented in core functionality?
Thanks
