I'm not seeing this. The collections tab looks the same to me as always (standard UI). Was this left out by chance? Or is that referring to "Sort by name"? I thought that was always there, but sort <> filter so I was looking for something different. By the way, thanks for getting Blinding and Fordel Midst into the Fast Travel window!
It is actually at the bottom, right side in the drop down where you search for collections by level, category, progress etc. So I thought it was the "Sort by Name" option.
So many thank yous! Being able to search collections by name (or partial name) is wonderful! No more scrolling through to find a specific collection! The additions to the Fast Travel window are also greatly appreciated. Well done, Devs!
