I couldn’t use #[2] without it.
Big day for me today….I used the bookmark feature on Damus for the first time. I get it now, hooked.
Discussion
Makes me wonder what else I haven’t been using lol
I could suggest some relays.
How does one use the bookmark feature?
Tap the … in the top right of the note and you can save it for later. 
Click three dots top right of note and select add bookmark. Then you can find bookmarks
Then click your profile image when you are on home feed page and you will have option to select your bookmarks from the menu that appears on the screen.
