This is speculative at the moment, just to be clear.
I am thinking about creating a profiler for NHibernate. This came out of the common need to actually get a good view about what is going on with NHibernate.
This is intended to be a commercial project.
I have a feature set in mind, but I would rather hear from you if you think that it is a tool that you would use (and buy) and what kind of features do you expect such a tool to have?
And, to forestall the nitpickers, I am well aware of SQL Profiler.
