The way SeeYou works with Waypoint and Task files was
significantly improved in version 7. The waypoint and task files are now opened
as individual files. You can open any of your Waypoint and Task files to add,
edit and remove them. Once you are finished editing you can File > Save this
file back to your disk. You can even open two or more waypoint files in
different formats and then drag and drop waypoints and tasks between them.
Additionally Waypoints and Tasks window have now become one window. You can
switch between Waypoint and Task view through the View menu.
