yeah but i cant make playlist more than just 1

On desktop

1. Click "my account". You should arrive at https://danbooru.donmai.us/profile .
2. Among the "Statistics", search for the "Favorite Groups 0" line, and click on the "0". You should arrive at https://danbooru.donmai.us/favorite_groups?search%5Bcreator_name%5D=zwo
3. On the top menu bar, click the "New" button. You should arrive at https://danbooru.donmai.us/favorite_groups/new .
4. Create a fav group.
5. You can add pictures to it e.g. by hitting the 'g' key on a picture page. (If you have more than one favorite groups, then hit 'g' and then type a number)
