Although that is not transparent to the user, the planner distinguishes between 
waypoint („Planerpunkte“) that the user entered and those that were computed by 
the planner. The latter are thrown away every time the plan is recalculated and 
the user is not supposed to change those (apparently we need to make sure the 
user cannot change them). The way to force a change to a deco gas at a specific 
point in the deco is to manually set the „Change to“ depth in the gas list. The 
planner will always switch to that gas when reaching that depth.

This I cannot reproduce. Please be more specific how to reproduce that 
behaviour.

The first thing is a known bug: The distinction between user entered and 
computed waypoints is not saved to the file, so upon loading them all waypoints 
appear as user entered when replanning. As a work around, you don’t have to 
delete all computed waypoints one by one but you hold the control key (command 
for Mac) when you click on the trash bin icon of the first computed waypoint 
and that will delete that waypoint and all following (that should be in the 
manual somewhere). Can you guide me how to reproduce the other apperance of 
waypoints?

You can do that with the „replan“ feature: You first plan the dive with all 
deco gases and save it to the dive list. Then you reopen it with „replan“ and 
delete the gas you want to delete and instead of „save“ press „save new“. This 
will add the dive with lost gas to the dive list in addition to what you have 
already. Of course you can repeat that for all gases.

The planner always comes up with the gases of the currently selected dive. That 
way you can plan a dive that is similar to an existing one. Or you can save 
fake dives to represent standard gas sets and start planning from those.
