DebugView filter editor
DebugView is a wonderful tool for viewing real time logging information generated by your applications. You can set filters which will colorize the output according to various rules. But the dialog for setting those filters is awful, especially now when it supports 20 filters.
So I developed this little application in Python using the wxPython GUI toolkit to make it easier for me to change the filters.

Supported versions
This software was tested using DebugView 4.31. Don't use it with older version, since they only support 10 or less filters. For future versions, importing and exporting filters from files should still work, but there could be problems with reading or writing the filter settings from the registry.
The filter editor will be updated to work with future versions as they become available.
Download
The application is licensed under GPL.
You can download the Python source code and run it or a standalone version which doesn't require anything else.
Python source code
You will also need to install these if you don't have Python and wxPython. This might be the perfect opportunity for you to give Python a spin. Try it, I've discovered it last year by accident and now I think Python is the greatest programming language that Windows developers generally don't hear about.
Standalone version
Unzip and run FilterEditor.exe.
