While the feature you discussed would be nice, I'm also looking for what I believe JA is trying to say.
I would like to enter my own categories that are from my network/site(s) like I do to any post or page to every page/ item of a list in list.ly (so each one has categories not only the list, though the list categorized in entirety would be a good first step, it's not my end hopeful goal), that are in sync with the categories that I have listed throughout my network.
Then individual items (I'm not sure if you call them entries or posts- each time I "add an item" to list.ly would show up in unique category posts and increase the amount that my list.ly is both of value to users, shows up in search internally and externally, can is relevant to the unique areas of which (in my case a large site with a lot of information creating personalized content driven user experiences with different user groups) would be able to easily find the information that I have spent so much time curating.
With this, also probably would go hand in hand, would be that individual items within lists could show as unique pages. To the front end user they do if I set it up in say slideshow view, but this way the pages would each be a unique post/page. That may be a different function, but I suspect it would be tied together with the ability to search by categories I enter internally (of course would be great if I could enter those categories in my tags in list.ly, but I'm trying to not ask for too much work.
I think that this would move list.ly from lists only to a more complete content curation system. I have done a lot of research on curation systems, and I know there are a lot of features. I personally really enjoy using list.ly and would love to see it grow to the level of some of the others that are more widely used at premium.
Thank you for all of your hard work!!
