Codeforces Curtain

This is an extension to hide the problems on the problemset page that are already solved by some user(s). "Which user(s)?" you may ask. Well, any users you add to the list in the popup. You can only add upto 5 users btw. Note: This only works on the problemset page. Just do the following after installing the extension: Step 1: Pin the extension. Step 2: Click on the extension icon to get the pop-up. Step 3: Enter a user handle in the input box and click on 'Add'. Step 4: Go to the problemset page and apply whatever filters you desire. Step 5: Once your filter is applied, click on the icon, and then click on execute. Something will happen behind the scenes and all the problems that have already been solved by the user whose handle you added to the list will disappear. If you add multiple users, for any particular problem, this extension will remove it if it has been solved by at least one of the users in the list. Another Note: It may not work on some problems, but that would be the fault of the codeforces API. I rely on the API response to remove solved problems from the problemset list. If a problem is not in the API response, it will not be removed. However, such cases are rare so don't sweat it. Hope this extension proves useful for you!
