Hey
,
I personally think that this feature is not needed and can result in quite a bit of unnecessary spam. Additionally, I don't know how complicated implementation of this system would be. If you haven't tried using
Push Notifications, I would give it a try and see if you still think the proposed idea is needed. Push Notifications are designed to support/address exactly what you are proposing.
Lastly, if you haven't read the sticky on proper way of posting a suggestion, I would check it out:
https://forums.d2jsp.org/topic.php?t=57896631&f=258. If you want your idea to get anywhere, you should include a poll as well as a visual representation of what this feature would look like.
If you had a poll, I would've respectfully voted no.
