Tie in with Nextcloud notifications
It would be really nice, if Element could tie in with the notification system of Nextcloud, so that notifications of new messages or mentions get listed in the bell/notification dropdown. I don't know if that is technically feasible, because i think that Element would somehow need to run in the background to receive messages or you would maybe need to use the matrix-js-sdk to receive matrix message notifications which then are send to Nextclouds notification system.
If this is added, users should be able to opt-out, as some users (such as myself) already have other push systems in place. Additionally, the server admin should be able to enable or disable this feature by default or force-disable it, since it may also significantly increase load of the server the Nextcloud instance is running on, especially in a multi-user environment.
