Retrieve Feed URL from Subscriptions
Clicking on the subscriptions will lead you to the feed's info site (tag channel/link) which is not necessarily the feed's URL, eg:
I think I can get the latter via exporting the the OPML but if there was a direct link on BazQux Reader, that'd be a great help.
It’s now possible. Right-Click on the feed in subscriptions list and chose “Feed address” menu item
I'm planning to add more advanced feed management in future where it will be possible to look for feed URL. I'm also planning to add an option to edit feed URL and you'll be able to copy URL without changing it.
