I occasionally use this filter on certain topics in my forum. Two examples: On Pictures of your latest ride continued - General - Unicyclist.com , on which users post lots of pictures, I like to filter posts by the user @turtle , known for his impressive mountain pictures, and I’d like to be able to share the filtered topic URL with others. On Exoskeleton & Riding - Unicycles and Equipment - Unicyclist.com , the user @MadHatchetAndy is the only member who shared his exhaustive experience of exoskeleton riding, which would make sharing the filtered topic very valuable, information-wise. The filtering button requests https://unicyclist.com/t/292153.json?username_filters=MadHatchetAndy , but the browser’s URL, alas, remains unchanged, so we can’t share the filtered topic view. I hope this is a reasonable request
