1. Timed profiles. My simple Nokia phone can do this! Select a 'temporary' profile (from the existing profiles that exist on the device) that will time out at a certain time or after a certain time. Otherwise I'm always forgetting to reset my BB off 'quiet' mode when I come out of a meeting, out of a cinema, or whatever.
"Big daddy" version of the above would, in addition, allow
2. Automatic changing of a profile on a schedule (e.g so it always goes quiet in the evening)
3. Addition of extra elements to a profile (over and above BB profiles) - e.g. a profile also has a home page image associated with it, maybe even a theme!
4. Schedule-linked profiles. Eg Automatic selection of a profile the the duration a calendar item shows time as "busy". Then revert back to previous profile.
A robust implementation of 1 would be great on its own
