    A list of all available Snapshots will be fetched after a connection to LongtermMemory and WorkingMemory has been established.
    These Snapshot names are presented in a drop-down list and the selected entry
    can either be loaded into WorkingMemory or removed from the memory/database.
 
    Additionally, it is possible to save the current content of the WorkingMemory under a new Snapshot name.
    The new name is provided via the text input field and "Snapshot_" is prepended to the name if it has been omitted.
