Currently, it's not easy to see the number of reviews of a course directly in the directory tab. I would like to filter my search results by the number of reviews and also rank my results by the number of reviews.

Also, I trust a 4.5 with 50 reviews much more than a 5.0 with 1 review, but there's currently no way to rank the first one higher than the second one. I found a blog where this problem is explained in detail and where a solution is proposed at the end: https://nbviewer.org/github/CamDavidsonPilon/Probabilistic-Programming-and-Bayesian-Methods-for-Hackers/blob/master/Chapter4_TheGreatestTheoremNeverTold/Ch4_LawOfLargeNumbers_PyMC3.ipynb#Example:-How-to-order-Reddit-submissions.
