Is there a custom, user maintaned repository that organize tags by topic?
For example I would like to browse (or find unaswered questions for) the general topic "software engineering" so it should include tags like:
software-engineering, SOLID, continuous-integration, OOP, dependency-inversion, IoC, class-desgin, SCRUM, extreme-programming ...
I then would like to predefine a query for me personally that give me all unaswered questions in a given general topic. Without having to specify all those specifc tags.
