The 4 categories give a rough time as to when a task should be done,
and reflect an assessment of the task's ease multiplied by its importance.
JCE - Allow arrowheads in the middle of edges
JCE - Support single, uniform font descriptors à la pango
? - Move generic node adjustment and spline routing out of neato
-ERG - New text labels with font elements <B>, <I>, <TT>, etc. (support via fontconfig or egregious hacks)
AB - smyrna
- 1 Design incl. 3D navigation, multiple graphs and viewports. Avoid modes.
- 2 Stable GUI. 3D mouse.
+ 1 QT
+ 2 Widget library. Plugins. Printing.
3 Full dotty replacement incl. history, checkpoints, scripting, undo.
- 4 Widget library. Plugins. Printing.
- 5 QT
- 6 General editor

YH/ERG - Clusters in sfdp
YH/ERG - Fixed nodes in sfdp
+ERG - Finish orthogonal edges (edge labels in dot; ports)

exposed port sides. Perhaps extend compass points to S, N, E, W to
mean anywhere along that side.
? - Tabular layout in rows and columns in dot (swim lanes)
+ Crossing minimization with some nodes in columns
? - Enable arbitrary depth clusters in neato using IPSEP
? - Allow mixed edge types within the same graph
<pre>
Generic label placement, with and without modifying graph layout.
Support for compound graphs.
+Allow varied layouts within clusters - recursion
Spline router improvement (Gordon's improvements, alpha adjustments, fewer
inflection points)
Fast incremental hierarchical layout
local name spaces
subclassing
Shapes - new parallelogram shape where angle is fixed for varying text
-Orthogonal layouts.
+True orthogonal layouts.
Support rank=min/max within the context of a cluster

Incremental layouts
-Dot with orthogonal, coalesced edges (e.g., <A HREF=http://upload.wikimedia.org/wikipedia/en/thumb/7/74/Uml_diagram.svg/700px-Uml_diagram.svg.png>this</A>)
+Dot with orthogonal, coalesced edges (e.g., <A HREF=http://upload.wikimedia.org/wikipedia/commons/7/74/Uml_diagram.svg>this</A>)
+Generalizing the above, support for hyperedges
Constraint-based layouts
Display of large-graphs (hair ball problem)
- relaxing constraining edges
- edge bundles
+ - other
Venn diagrams
Integration of geographic info - maps
Aspect ratio in dot with clusters
Dot with fixed width
-Crossing minimization with some nodes in columns
Adjust graph to allow no edge-node overlap with line segment edges

<H2>Done</H2>
ERG - New orthogonal routing code
JCE - use floats not ints where appropriate
YH - Filters for Matrix Market
+ERG - New text labels with font elements <B>, <I>, <TT>, etc. (support via fontconfig or egregious hacks)
