So, if any information is to be moved out of the Notes Tab an additional new tab is probably not warranted. However, this means that there would now be a third tab that contains editable data fields (apart from Notes and Equipment).

This does change the notion of the Extra data tab a little bit, but the way this is defined today maybe only makes sense if you wrote the code - from a users perspective this distinction (basically, this tab shows the information we get as string data from the dive computer) is maybe less obvious - I guess it could be defined as dive computer internals or something.
But let me ask you, why add it to that tab and not use the Information tab? This one already contains another (mislabeled, I notice) field that some people might want to edit: dive time (which should be dive duration). And it contains the atmospheric pressure. So instead of adding this to Extra info tab, wouldn't it make more sense to make some of the fields on the Info tab editable? I don't think it makes sense to allow users to edit things like the Interval or CNS / OTU, but I could see editing duration, air pressure (atmospheric pressure would be a better label, but air pressure is shorter), water type (specific weight, really) and air temperature (oops, that's not in sync with the Notes tab for me) here?


> 2) If the above were true, the UI would be simplified if the tabs with editable data fields were grouped together. That would mean rearranging the tabs so that Extra Info is in the third position just after Equipment.

That's the position the Information tab is already in, another advantage of my proposal.

> 3) I suggest that the two temperature text boxes are moved to the Extra Info tab. The water temperature is depicted in great detail on the dive profile, so no information is lost.

They are both already on the Information tab - except, as I said, Air temperature is not in sync for me. Need to look at the code why that is.

> 4) I expressed an opinion beforehand that any information that affects the deco ceiling should be immediately visible. One of these is the dive mode. When logging a dive, I often found that Subsurface defaults to a wrong dive mode. My Petrel does not provide the information, therefore this has to be set by hand using the Dive Mode dropdown box. No fault of Subsurface. Therefore my strong preference is for the Dive Mode dropdown box to be kept on the Notes tab and not moved to the Extra Info tab. If indeed, the Dive Mode dropdown box is moved to the Extra Info tab, I would expect (almost 'demand') a clear indication on the dive profile that shows the dive mode. (Maybe as part of the deco model info e.g. "VPM-B +3  (Open Circuit)" or "GF 40/75 (CCR)").

I like showing this as part of the deco model info.
And I think the majority of our users are OC-only divers. So we COULD move this to be only on the Information tab to de-clutter the Notes tab. But then, I don't see this as a requirement since if we do that the tags entry gets quite long...
On the flip side - for me the notes field is always too small... so moving tags up to be on the same line with date and time (where right now we have air and water temp) and have air temp, water temp, and dive mode all on the Information tab... that I could easily get behind :-)

> 5) I propose that the Atmospheric pressure datum remains on the Notes tab and is not moved to the Extra Info tab. The reason is that, for inland dives, this is likely to be crucial information with respect to the deco ceiling. I regard this information as so important that, if this datum was indeed moved to the Extra Info tab, that it should also be indicated somewhere on the dive profile or on the Notes tab. I must confess that I am probably biased because I do many inland dives over 1000m. For me this would not make a difference because my dive computer records atmospheric pressure in calculating deco. But many other divers that dive these same sites do not have access to atmospheric pressure and without having done Dive-at-altitude training and I have seen what altitude can do to the deco ceiling. Therefore my emphasis on this matter.

Well, we don't have that on the Notes tab right now. Alternatively to my proposal, this could of course be put in the place of the air temperature. Unsurprisingly I like my proposal better, but let's see what others think.

To make it clearer, I suggest we have the Notes tab only show

And that we add the dive mode to the Information tab and make some of the values there editable.

However, this is the sort of matter that needs some form of broad consensus before starting with the changes, otherwise a lot of time can be wasted in rewriting code.

Completely agreed.
