This simple mod allows a player to create their own waypoints in space, as well as remove them.
To use it, you will need UniGUI 1e or greater installed.
To create a waypoint, just open UniGUI, then open the UniGUI Extension Menu and then select 'iWayptUtils: Create'. To delete the selected waypoint (your current target), select 'iWayptUtils: Delete'.
To install, just put this zip file in your IWar2/mods directory and select "Waypoint Utilities" in the I-War 2 Extras Menu. You will also need to select UniGUI in the Extras Menu.
