By "study" I mean a hypothesis and a 2 minute test lol.

Anyway, what I found is that aircraft handle much better on the deck if there is a mechanism that folds the vertical stabilizer 90º to one side. This could be;
A. Atheistic, as the whole tail folds,
or
B. Hidden, where just the internal wing is folded and the appearance of the tail does not change.

Reason:
The carrier is moving forward at 18 mph. This essentially means there is 18 mph of "wind" flowing over the whole plane, more specifically the tail section. As this "wind" flows over the horizontal stabilizer, the plane naturally wants to point into the wind. While great for takeoff, this makes taxing and using elevators difficult use. By rotating the horizontal stabilizer, you get rid of that force, and thus the plane will stay pointed in the same heading. In short, you're taking the horizontal stabilizer out of the airstream.

Conclusion:
I don't know if I'm the first person to discover this idea. This idea could probably be improved upon using FunkyTrees, where it only rotates under 18mph and under 120 ft (10 ft above carrier deck more or less) but thats besides the point. The system would only add 1 part to any plane, so in my opinion it's worth it.
