Feedback on Pharo 1.4 Debugger

The debugger in Pharo 1.4 is looking very nice - cleaner and easier to
follow.   I wonder if the following might be an additional improvement...

If you consider a class has a method subpart which has a block subpart,
then the "natural flow" of these would continue from left to right.
Referring to [1] - having the "Block" text on the left breaks this sense
of "flow".   What I've drawn in [2] feels more natural to me.

Possible advantages:
* It is easier to see the five SystemReporter items line up.
* Balances brevity with giving a bit of context to distinguish nested
blocks.

Has anybody tried to partially highlight the other shared activations?  i.e. in the below if you selected any of the updateReport activations (home or blocks within it) the other activations could be highlighted in a lighter colour.
