Can anyone tell me how to use it. I am using sublime text. When i click on the + button on a problem page(after installing the chrome extension). A green arrow kind of thing passes from left to right and nothing happens. I would appreciate if someone can tell me what wrong am i doing?

This question was asked to someone who posted the blog on Leetcode & when i saw this i couldn't comeup with anything effiecient so i added a blog here for help.
