Genuinely thank you for the feedback! My first thoughts:

• Two columns wouldn't work on mobile. I could serve different pages based on device but I'm lazy and that seems like a lot of work right now.
• Numerated entries are a good idea, but the numbering would change every time I add/remove feeds if I want to stick to alphabetical ordering, which kinda defeats the purpose.
• For last update do you mean last time the feeds were fetched or last time I modified the index page?
• New podcast highlighting would be nice indeed, but it would probably have to be manual.

My first general problem is that right now I'm serving a static page with a reverse proxy, so it's difficult to implement backend logic. The second problem is that I

• am not a frontend dev
• am bad at frontend dev
• hate frontend dev.

If someone has suggestions on how I could implement stuff like this without moving to a web app with a backend I'm all ears.
