Well, they did de-emphasize in their marketing the (formerly rather focal and foregrounded) impression that OG could (like many packages, including MS Office) automatically generate standard orthogonal trees, with parent nodes centred over their child-ranges.

Beyond that, the only response more eloquent than the silence on this forum has been the standard email formula that "we have filed this somewhere and it may receive attention if it is ever foregrounded by due democratic process … etc etc".

In short, I would really not be all that surprised to see this family of bugs (undecipherable overlapping links etc etc) reproduced in OG6.
