Plugins/Modules

[eluser]Unknown[/eluser]
Hi I'm new to CodeIgniter and for that reason I need a little help.

I'm doing a research for technical information on several PHP frameworks. The purpose of this research is the development of a management system for the company I work on. What I'm trying to know is that if CodeIgniter supports the development of a Web Application that supports plougins/modules. I know CodeIgniter supports plugins but those plugins are for the CodeIgniter core, right? What I want to know is that an application built using CodeIgniter can support herself plugins.

Thanks.
