I only just saw this post and had a look at your presentation PDF, application and source code. I haven't watched the video yet but look forward to checking it out later tonite...
I would like to ask if you'd like to contribute the PureMVCPopupManager class. This appears to take the source snippet and subsequent discussion / advice of this thread: http://forums.puremvc.org/index.php?topic=105.msg367#msg367
and turns it into a concrete useable class. And it adds modal and centered params. And a demo.
It's just one class, but it's a great implementation. I'd like to put it into a repository and have it available as a standard utility. The repositories are filling up (30 projects so far!) and the goal is not only to have demos to show the way, but to start to fill the shelves with 'off-the-rack' solutions to common problems.
I wonder if you'd care to 'own' the project? We'd credit Daniele Ugolett as well, (who contributed the original snippit) in the code attribution. It'd be great to have your demo in the repository as to show how to use the utility.
If you'd be interested in contributing the demo and utility, have a look at the Contributor Central post: http://forums.puremvc.org/index.php?topic=142.0
for a little info about how the community contributions are being handled. Or contact me separately and I'll give you a peek at what's going on.
