I think it would. Having the ability to edit entries could prove useful under different situations. I see that it notifies you if you try to add a duplicate; That's pretty cool. I enjoy this project quite a bit, and it has sparked some interest in bookmark sharing in general. Thank you for this.
Thank you. I'll add the edit functionality shortly. I'm glad simple bookmark sharing is something that you like. After building it for just my friend, I see more and more use cases for it. Someone is already using it to share links with their classes.
