does this refer to the fact that the grid/scale moves under the mouse pointer when you drag points? As this will be improved. Or anything else? You realize you can also move the waypoints in the graphical display using cursor keys?

That’s why we offer both options.

yes.

By default it copies the previous mix.

The gases that it (don’t call subsurface “SS”, Dirk does not like that for obvious reasons) starts up with are the gases that are used in the dive that is selected when you start the planner. That is meant to allow you to “plan a similar dive to the one selected”. If you adhere to a diving philosophy that has a standard set of gases you could make a dummy dive that uses those gases and always start planning by first selecting that dive. For the manually added waypoints the user is responsible to select the correct gas (again assuming that it is the same as the previous segment, so you only have to enter it once per gas change not per waypoint). In deco, gas changes are inserted accruing to the “Switch at” column in the gas table. That is pre-filled according to MOD using a (not yet user configurable) pO2 for deco.

As I said, that depends on MOD (and thus pO2) or manual depth setting in the table. With pO2=1.6bar it wants to change gases at 22m (as that is the MOD). Shall we always make that multiples of 3m?

> #7 dive plain details text box should be a table or somethig which permits a better formatting. BTW Decoplanner has a table but it doesn't permit to copy and paste nicely the plan on a email.

I don’t quite understand. That is a (html) table. When you cut&paste that to your word processor, you should be able to apply any formatting you like.

You mean subtract the time of the last manually entered waypoint from the total run time and explicitly state the depth of the first computed stop? The first I can understand but why would one one the second?

Best
