1)Self Managed dependent fields, totally agree, would also like to see them linked together, you choose a country and you get a nice list of cities to choose from!

2)People you may know, totally agree, maybe we could re-write the way it works to use the matchmaking functions, so it would be easier to make a suggestion based on colour or anything.

3)The way D7 is developed, seing separately the Wall, Images,Sites,Videos,Sounds , it would be a hard thing to do, because we'd have to tweak each see more of them separately to add up in a single function that will bring the activities to the user.Wall should unite all these into one section, it already has the feature of activities.
