I think it might make sense too @dlunde. First I used the "mode" of the CFG view as they had few "commonalities" (they are relevant int the same phases, they both have blocks and edges between blocks, etc.) but they are in fact 2 different graphs.

I'm not sure I understand what you mean @robcasloz: if there is a separate view for the dominator tree, there is no need for a dominator tree option.
