The list of notifications is really important if you have been active on this network.
However, the list is really very poorly organised. It should clearly differentiate between likes and replies. I don't need to followup on likes but I probably do on replies. At present it is very hard to scan the list for replies.
In addition, it is totally unclear which things I've looked at and which I haven't.
These things continue to add significant friction to the use of this network and make it a very unprofessional experience.
