Feature Request : Save Post/Ariticle

@LeetCode It would be a very great feature to introduce the Save Option for the Posts/Notes in the leetcode.

As we know that the community keeps on posting High Quality Posts and we often find it lost somewhere under excessive posts, In this time of huge data and information we find it quite difficult to organize the Important Posts.

It will be quite helpful for all of use to better organize our information and there is no more overhead of loosing important articles/posts.
