We'd love that. Like most open source projects, we are always looking for
more contributors.

First thing to do is join this mailing list. I added your address to the
approved sender list, so future emails from you won't be held in
moderation anymore...

I know that after having tried this the description seems obvious, but in
order for us to reproduce what happened it's best to give step by step
explanations.

- open planner
- which tanks / gases are in the list?
- which waypoints have you defined?
- when / where do you add the gas change?

Again, I think we might need more details.

How do you modify the plan? That's still something that has a lot of room
for improvement. It's way too easy to get Subsurface confused.

Good idea
