A user will be able to get notifications when background events happen, for example: when another user or guests accepts / rejects invitation to a timeline, or new timeline or workspace is shared with the current user. There will be an icon with a number of new notifications, that will open a list of notifications. Each item in the list will contain description of the notification and, optionally, will take the user to the relevant page in the system, where an action can be done on notification. Notifications can be dismissed: some notifications will be dismissed by just viewing them, others will require some action to be taken.
