Hi all,

I am using vacuum-opengl and vacuum-ubigraph to visualise and analyse some of my data structures. They are quite helpful most of the time, however sometimes I feel the need to tweak the generated output -- such as removing the auto-generted identifiers from constrcutor names, pack some things together, or similar.

Is there a way to configure their output?

And for the vacuum-ubigraph option, I like it's output generally, however while creating the expression tree, is doesn't respect my structures. If there is a flag or so to fix this issue, I'd appreciate it. The Problem is like the following:

data Expr = Sum Expr Expr | Mult Expr Expr | Single Int
e = Sum (Single 2) (Mult (Single 3) (Single 4))

And it orients the tree in such a way that Mult looks like the root node, instead of Sum, as I would expect.

Thanks,
Ozgur Akgun
