ElggCamp Santiago Workshop

Hi guys, tomorrow Brett and I will be offering a WS at the ElggCamp Santiago.  The goal is to bring some ideas to develop right there! so I'm asking you for small-and-quickly-to-code* features you think will be nice to have for Elgg 1.8
Fell free to suggest anything you believe can be coded in less than 3hs (as alpha version), the idea is to get people involved.
We will be starting at 1PM Time of Santiago (-4)
Thanks in advance!
