Suppose my tree structure is as so:
* a
** b
*** c
* d
** e
*** f
*** g
*** h
Gingko lays it out like this: a b c
d e f
g
h
If I'm in the far right column, let's say I've highlighted item g and go up to item f. However, I hold the arrow key down a little too long and overshoot to item c. This causes everything to the left to suddenly jump around and disorient me.A related issue, the layout suggests that c-f-g-h is an intended list when it isn't. It can cause readers to become confused if they're reading normally in one column and don't fully realize they've jumped to a different branch in between c and f.
