Creation of Plugins/Gadgets for the Sidebar

[Alexandre Vázquez <alexandre vazquez gmail com>]

Hi to everyone!

First of all, I want to introduce myself. I'm Alexandre Vázquez (Alex) and I want to know some of the details of the design of Gnome Shell. I'm reading the Design Document written by William Jon McCann <william jon mccann gmail com>,Jeremy Perry <jeremy perry redhat com> dated in 14 November 2009, with the idea to integrate a application inside Gnome-Shell. But I already have a few of questions about that. Sorry I they are very stupid or illogical. The questions are:

• At this moment, I can create a 'gadget/plugin' that interacts with the Sidebar of the GNOME Shell?
• At this moment, I can create a 'gadget/plugin' that interacts with the 'Message Try' (Down of the Screen) of the GNOME Shell?
• At this moment, is there any documentation that talk about this proccess?
• At this momento, is there any 'gadgets/plugin' inside the gnome-shell trunk?

Thank you very much for your help, and sorry for the time you're wasting to read my mail. 

Cheers,

Alex
