I am one of those who are astounded by the power of LogParser. I think a lot of people have not discovered it because they are put off by the command-line interface.
I am attaching a gui I have created in C# along the principle of KISS. I realize it is pretty basic but I see it as a starting point. Based on whatever feedback/assistance/tips I receive, I will develop it further.
I am providing all the code in the hope that anyone who sees errors or ways of improving it will help improve it.
