You are right, it would be really helpful if people would also return back and post their solution... I sometimes ask for that too because it can help somebody else in the future as well.
So I definitely agree with you and thanks for sharing your thoughts with the community! I believe that our internal team responsible for DevNet portal is also preparing some new features that will help us all to keep DevNet portal tidy and usable as much as possible so stay tuned! I'm personally looking forward to some of them :)
Best regards, Martin
