In insulation that may be true. But our existing UI is not up for discussion.
And that very intentionally has the information that the user interacts with
(information tabs and profile) on top, and the selection of dives on the
bottom. Switching that around to show statistics would lead to a horrible user
experience.
On mobile these would have to be different pages, anyway, so there the 'layout'
question is fairly moot

Every time we opt for "oh, let's make this selectable" we significantly
increase the amount of code that needs to be written and tested, and we make
the UI more complicated by adding more options.
We already have way, way, way too many options. And we constantly find that yet
some other feature has bit-rotted and doesn't work anymore. Or that some
changes to our code break something else that doesn't have an active developer
anymore.
Today Subsurface is de facto maintained by about five people, three of which
contribute in very narrow slices that are "theirs", and the other two (Berthold
and I) try to keep everything else working.

It's definitely an idea. It's geeky and cool. I don't think it will help
accessibility (in the sense of being easy to understand for the casual user).

You mean time / categories should be the x axis, correct?

Which dive display? The dive list has time as the vertical axis. Do you mean
the dive profile? That's a single dive, not a collection of dives. Very
different.

Yes, that makes perfect sense for a dive plot (which is why we do it that way).
For statistics I would find it absolutely painful.
