Project Manager

I am currently working on creating my own project manager written in the CodeIgniter framework. I plan to have the application work like a desktop, where every aspect of the manager lives in modular windows (using the jQuery UI) and you will never have to leave the main page while using the application.

So far I am just working on the base functionality, which will include project information, creation, etc. Client management, individual compositions linked to individual projects, time tracking, invoicing based off of tracked time, and to-do list/alerts based off of information in the project database.
