This Chrome extension banishes podcasts from the Spotify web player user interface.
This is a very simple Chrome extension which just does one thing - it hides the Podcasts bar on the Spotify web player using CSS attributes. Finally! No more Joe Rogan et al. Rejoice :-)
You can tell if it's loaded because it also changes the background colour of the main page area to a subtle dark blue.
Source code, such as it is, can be found on GitHub:
