+Events and Event View
+=====================
+
+Vault events give information about the vault's status and certain activities.
+There are several types of events, including conflict detection or corrupted files.
+All vault events are logged in the event view, which can be opened from the main window.
+
+.. note::
+
+    Vault events are not persisted on the hard disk.
+    They are only stored in memory and are lost when the application is closed.

+
+Event View
+------------
+
+The event view shows the events of all vaults.
+To open the event view, click on the Bell icon in the lower left corner of the main window.
+If new, unread events are present, the icon has a small red dot.

+
+The event view has an action bar at the top followed by the actual event list.
+Events are displayed from newest (top) to oldest (bottom).
+You can filter the events by the vault they belong to.
+Also, you can clear the event log by clicking on the trash can icon.

+
+Vault Event
+-----------
+
+A vault event consists of a title, its number of appearances in brackets, an affected file, and a timestamp.
+If you hover over the event, a button to open a context menu appears.
+The context menu contains event-specific actions, mostly to reveal affected files in the file manager.
+
+If the vault of the event is locked, the event is anonymized.
+To view the event details, you need to unlock the corresponding vault first.
