How to insert a flypoint into a flypath

If you need to edit your flypath(1,2,3,4), you can delete single flypoints(1,3,4) or add a flypoint at the end of the flypath(1,3,4,5). In case you want to insert a flypoint (1,6,3,4,5) you have to go into MAIN:flypath
where you find your flypath and the flypoints. By ranking the flypoints with the tree editor you can set them to the order you need.

P.S.: a button in the Presentation Edit Panel to insert a flypoint would be nice...
