Brainstorm

I can't find the 'feature request' category, so I'm openning here.

Sorry if this feature already present. But I will love to see something like
'choose profiles'.

Example, during day period, I would like to setup my N900 for business. Where
my profile is completely configured for company. Gtalk, MSN, Email, etc. etc.
etc. and in night, I would like to use it as me (person), with my personal MSN,
Gtalk, Email, etc.

This feature can be an excellent feature to be added if it is not already
present. And if this is possible, just tell me how to do it and sorry for open
this... :D
