The +bonfire playground has been updated with a few fixes and improvements. My new favourite screen is this one which feels like a forum focused on your interests: playground.bonfire.cafe/topi...
You should also notice snappier navigation between feeds and discussion threads, especially when clicking the back button to return to the feed after having read a discussion (where you'll instantly be back where you were, rather than the feed being reloaded like before).
As always, please share any feedback or issues!
