So far I have been suggesting new features to http://delphi.uservoice.com
Since it is managed by Nick Hodges (who is no longer an employee of Embarcadero) I decided to report my future improvements requests to http://qc.embarcadero.com
Is QC this the right way to go or is there a dedecated Idea Share solution I am not aware of?
Just as a reference I will point one of my suggestions Add Patterns.pas to allow easily document code
Please advise which is best place to submit such stuff to?

QC is the only official place for end users to report bugs or make suggestions. While alternatives like uservoice might be nice I’m not aware of any Embarcadero employees actively monitoring that site.
