CodeIgniter
Dwoo implementation - Use the Dwoo templating system with CodeIgniter in a very tidy way.
Template library - Construct complex page templates using layouts, partial views with support for modules and themes, meta-data, breadcrumbs and automatic/manual page titles.
Prowl library - Send iPhone notificiations from your CodeIgniter application with Prowl.
I'll be adding everything else shortly.
For now, have a look at my GitHub profile for my CodeIgniter libraries such as REST Server, REST Client, CLI, Cache, Asset and of course PyroCMS.
