Right now my biggest gripe is I can't tell clusters to go to a specific rank. Although enabling "newrank" helped a lot, clusters I want to be the first, or last of the whole graph, still end in the middle for whatever reason, resulting in lots of edges that curve backwards, so the graph overall shape instead of looking like a diamond or a wrapped candy, instead looks like a big mess with lots of U shaped edges that go all over each other resulting in something completely impossible to read. EDIT: also, being able to create "venn diagrams" of sorts with subgraphs would be awesome, basically allowing a node to be in several clusters, and have the clusters borders cross each other so that the item is inside all of them.
