many times i need to give site administrator option to set cron jobs. some plone interface would come in hand here. i'm already preparing specification for this project and should be ready in few days.
when having a comunity site its hard to drive people back to your site or to make it more attractive. facebook does it perfect. tagging pictures with users (or sending mails if they are not part of the site). plone implementation is needed here for sure.
well this is more local one. in slovenia we have search engine that also provides maps, just like google map, but better for our area. so this would be the implementation of all their webservices into plone. still need to look a lot into this area.
i didn't see any product that would provide some nice interface as well for administrators and users or some nice developer tool to easily implement this functionality into plone. i guess i must make some search for this kind of tools and then to write some abstract about it.
well this is the last in the series of ideas :). i found WatermarkImageField, but its only for plone 2.1. so implementation for plone 3 is needed. code is already prepared for other developers to use it but i would also like to provide a configlet where site admins would have a choice to enable or disable this feature for image fields over any content type.
well this is it. hope i would also get some sponsors for this kind of ideas.
