By the way, another thing. Crosslinks between tracks in circular diagrams also work in a weird way. You can see a picture here: http://itmag.es/2B8MM . Why does it connect closely located regions with such huge crosslinks, which go around the whole track? Why not connect them with arc going counterclockwise (inside --> outside)?

Peter wrote the crosslinks, but I think that this behaviour occurs because the motivation for including them was to represent connections on linear diagrams. On linear diagrams, it doesn't make sense to cross the origin (i.e. to go off the page to the left, then come back in on the right). The circular representation is currently, I think, a reapplication of the same logic in the circular context, rather than a rewrite specific to circular images.

And also crosslinks are hard to see under track features, but that might be caused by the first issue.

I'm not sure what you mean - do you mean that the angle at which the crosslinks come in can be so shallow that you can't separate them by eye?

Cheers,

L.
