Hello all,
after reading this discussion, I decided to create a little userscript that inserts the link of a practice problem in the page of the related contest problem. A userscript is some javascript that is injected into a page through a browser extension. Its purpose is personalization of web pages.
Issues: Sometimes the link is not inserted. In this case, try to reload the page. I don’t know the root cause of this behavior but feel free to submit a pull request if you figure it out.
Want to upvote, but can’t due to low karma!
