EditorSettings
Editor settings consist of topology-specific settings, and user settings. Topology-specific settings are stored in the topology, meaning that they apply to all users of a topology, while user settings are stored for the current user account, independent of the topology. Whether an option is topology-specific or user-specific can be determined by its position in the topology's options tab.
The safe mode is enabled per default on new topologies. It prevents accidental data loss when users click the topology destroy or stop buttons in the menu by asking for a confirmation. Experimenced users can disable this safety checks.
To help users build nice-looking topologies, the are the options Snap to grid, Fixed positions, and Big workspace.
Snap to grid will make all moved elements snap to an invible grid. This way it is easier to align elements.
Fixed positions will disallow any element movement. This will help prevent accidental element dragging.
Big workspace will draw a huge workspace, which is useful for designing topologies with lots of elements.
The option colorify segments will when activated display the links in colors. Links in the same network segment (layer 2 network) will get the same colors to make it easier to identify network segments. Network segments consisting only of one link will be displayed in black as normal.
Switches and external networks do not seperate network segments while other elements like virtual machines do by default. This setting can be changed in the attribute window of the virtual machine ("Segment seperation"). Note that this setting will only help the display and does not change the actual forwarding behavior.
This option displays the IDs of elements, connections, and the topology in their respective right-click menus. This makes it easier to access the respective entities via the API.
This option displays the site of elements in their right-click menus.
The debug mode activates an addtional "Debug" button in each elements right-click menu that displays internal information about this element. This can help developers and administrators to debug certain situations.
This shows connection controls (i.e., the handle for connections, and the interface elements) on connections. This is important to control the topology, but it may be useful to disable this option when taking screenshots.
