Hello.
I apologize in advance if this is the wrong list for suggestions for Mondrian, or if what I suggest has been implemented and I just haven't been able to find it.
Missing layout: Rectangle packing. There have been quite a few times when it would be -really- convenient to have the smallest possible rectangle, but all of the layouts seem to waste space to some degree, unless the data really -should- be stored in a straight line.
Missing feature: a way to have labels which are always visible, but perhaps only legible on the larger nodes. [What inspires this is trying to look at a callgraph using SugiyamaLayout, which works very nicely, but not being able to label the nodes without it suddenly being several times wider; the visual information gets entirely lost in the sprawl.]
