Now unnamed waterways are mixed with named ones, and as they are grouped by name, unnamed ones from a "tree" that push them up in the list. I'm trying to tag names in OSM on the waterways that have one, and this grouping and the unability to filter them makes it harder.
It would be helpful that waterways tagged with noname=yes were in another list or at the end before named ones (or no named but without noname=yes)
