Nostrudel unfortunately makes bloated lists with lots of duplicates, concatenating the whole list at the end of the current list when I add another user.

Here's how my carefully named lists created in Nostrudel display on nostr .band, which also has list management. 🤷‍♂️

That list with 574 actually has 40ish unique users, and a huge amount of duplicates 🤦‍♂️

It's a sorely needed feature that's an absolute mess.
