Hi,
I think of a new feature of CB: customization of the start page for registered users, along the lines how it's done on My Yahoo start page or Google Start Page. Users could choose the content (basically modules) they'd like to see on predefined positions. Say, I could make the right column available to customization - there would be some kind of a selection widget (a drop-down list or a context menu), and the options would be stored in the user profile.
This would mean hacking the core, probably, or encoding a special positining-and-storing-only module.
What do you think?
Best,
Marcin
