Excellent idea. I'm seeing that method more and more with extensions. Nice JS dropdown with filtering and checkboxes. Much preferred. Might want to think about building a Joomla backend filtering addon for the article manager from that work (reuse baby!). On a site with 66k articles, it would be VERY welcomend
BTW, the developer plan is the only way to roll now! Love the support and access to goodies. We just revamped the payment system on this massive site with 30k subscribed users and 66k of articles from OSE Membership and JFBConnect to CBSubs and CB Connect. Works terrific and has created a great user experience.
We did find one addon that was a must, BTLogin module which has done a fantastic job at integrating the full CB Login module and when CBConnect is enabled, automatically uses your APIs to set all that up. Brilliant...
With a bit of tweaking, we sped the site up 2fold over the weekend and made it WAY easier for new subscribers of urotoday.com
