1. and 2. are allready part of another solution (they are actualy not a part they are another solution top there)

if you want to split out with your idea for advanced groups, delete your solution (guessing that it is yours) and create a new brainstorm item for "Contact groups application - desktop widget" or alike...
it would depend on an implementation of "Contact grouping". This is also not part of the "Enhance Phone App" topic and should have its own brainstorm anyway.

Thanks
