This is really useful! Cf. e.g. 58b87aa4dc3b.

Sometimes there is distracting output by the "auto" tools: e.g. at 
a "Code generator: dropping subsumed code equation" by Auto Quickcheck 
and at 
a unification trace from Auto solve_direct. I guess it would be the task 
the tools to omit such outbursts and not globally on the IDE side?
