One Improvement about ratings and tags

[vishal-kumar4]

when we click on any ratings and if we had an option that we can get problems based on tags so that users can prepare topic wise it will be a good improvement like if we can have the list as shown in the above. I personally felt that c2 ladders was very helpful and if we can get this somehow it will be more useful to the users. I did some work and its working fine I can help and contribute to this feature if it suits you.
