Set custom feature_level_height for each GraphicFeature #87

Is it possible to set a custom feature_level_height for each GraphicFeature, rather than a single global value for GraphicRecord?

If I understand your intention correctly, then I think unfortunately no, it's not possible. Also it will likely be not implemented either, as the key problem this software solves is arranging the features in a non-overlapping manner, i.e. grouping (assigning) them to the lines (or levels) on the plot. The algorithm in DNA Features Viewer finds the minimum number of levels that allows plotting the labels without overlap; the heights (levels) are really categories, not distance. This approach works well and simple when the height of the levels, that is, the height of the letters, are the same.
