Adding top level dive to a trip is rather awkward. Have to create a
new group and then merge to previous.

Merge trip with previous is mis-leading as it is currently merged with
the one above (with my normal sorting order this means merging with
next trip).
Possibility to merge with previous and next would be cool. However,
once merging selected dives or groups is implemented this might become
obsolete.

If you remove a dive from the middle of a dive trip, the trip will be
split to two trips with a single top level dive in-between. (This
makes sense when you know the design but is probably quite confusing
for new users without background knowledge.)

When opening a log file and enabling the grouping...you have to quit
subsurface and start again to get the automatic grouping
"initialized". It would be cool if the grouping would occur on the UI
when enabling. But if there is technical reason behind not to do it..
at least inform the user for the need to re-start.

Trying to import older XML file to current one results in a crash:

I guess this is the same as sorting by any other column than date.
