I'm a huge fan of your product. Have tried af lot of other apps and software but i keep comming back to SD.
I just have a few things that would make my day easyier.

- As a helicopter pilot i often fly to LZ outside airports. And the SD map is unfortunetly not that detailed. Would it be possible to get a more detailed map, like openstreet map as an layer?

- weight and ballance for helicopter, maybe possible to get the envelope for latitude as well?

- I really like the briefing pack, would it be possible to attach notes to the pack, personal i would use it to describe LZ or make my take-off and landing distance when i fly fix wing.

- Support for Garmin GDL39.. yeah i know garmin,, :/


Thanks for a great product

We do already calculate lateral weight and balance for helicopters, but we haven't added an envelope for this feature because very people have asked. If others are keen on your other feature ideas I'm sure they will reply here.
