of the latest query" list and can be added to the investigation with the "Add to inves- tigation" button

• Menu button (next to hide button) which can open the menu of the box
• Add memo button (in the menu) to add a comment box
• Delete button (in the menu) to delete the subtree of the box
• Move to new button (in the menu) which is used to move the subtree of the box into a new investigation
• New investigation button (in the menu) which is used to start a new investigation from this box

Investigation boxes can be moved on the screen using the mouse (drag and drop).

Management of investigations

Investigations can be saved ("Save investigation" and "Save as..." buttons) and loaded ("Load inves- tigation" button) using the investigation list located on the bottom left. It is possible to filter saved investigation (My and All investigations, dropdown menu above the list). The items of investigation list can be deleted (only the own ones of the user) and shared. If you share your investigation, the other user will be able to delete it or edit it. Your investigation can be edited or modified when the database is unchanged (compared to the database at the start time of the investigation). If the database has changed, you cannot edit or change the investigation.
