Add "Pick One" button

🚀 Feature Proposal

This button circled in the image is the Pick One button. It picks a problem with a similar difficulty to your recent submissions. This could be very helpful for those who use leetcode as a daily exercise. Please add it into this addon!

Using leetcode show directly, we could randomly select a problem, yet it does not take recent submissions into account.
