Hey Dave -- I saw the issue you reported, but haven't had a
chance to look into it at all. I haven't run into the problem you
report. Yes, it's a maintained plugin, though obviously hasn't seen
any recent activity.
Frankly, if the visualization capability is interesting to you,
BuildTracer has the advantage over Template Profiler.
I think Template Profiler's interface has some nice ideas that
BuildTracer doesn't have at this point, which is why I was trying
to evaluate it. They take slightly different approaches to solving
the same problems, which could be a good thing.
I might end up looking at the code bases in comparison to each
other to see how different they are.
