Hello, I noticed two new features in Athena 0.8.040 and am unsure of how to use them. The new features are "Importance" and "Edge Step". I attempted to use the Edge Step feature by checking "Fix Step" and then entering a value, but the Edge Step always reverts back to the automated value. However, when I use the Increase/Decrease buttons (Left/Right arrow in Edge Step window) the edge step does change, but it only changes in increments of 0.01 which is much too large for my datasets. Is there something I am missing here? Also, I couldn't locate Bruce's changelog for Athena so I am unsure of what the new "Importance" feature does. Anyone used this new feature yet?
