Someone needs to make better archives for medium. It would be super simple and definitely catch on among some members of the community.
The current archives suck. I have written daily blog posts for 2 years + and there is no way for me to easily sift through all of my writings.
Use the Medium API to fetch this data and sort here. Freemium model – pay to get more than 6 months of archives (or something like that). Would appeal to Medium power users.
