GEGL does not structure operations in a tree form but as a graph, the XML file format of GEGL uses a tree with clones. Both are valid options, though there are some types of graphs that might be desirable that are not possible to express as graphs. For an editor for meta-operations (like unsharp mask, dropshadow etc. a proper graph editor could be mose suited.) > My personal take is that there probably is a topological sort > algorithm which "effortlessly" leads to an easy to understand > description of the tree in list form.

But that does not have to impinge on how a UI is done. /Øyvind K. -- «The future is already here.
