There were times I had myself saying “This would be a good addition to PODS”, but I always ended up coding it myself as standalone or plugin. I would definitely make a brainstorming and tell you my ideas. The thing is I am overwhelmed by projects now, but the first thing I would do is promote this plugin and write some tuts when my blog is up (its cooking).
Really, if wasn’t PODS I would’ve tried to code something similar myself or I would’ve switched the CMS :).
