I've seen several people mention EQ6 but very little about Quilt Wizard.

I have it and I like it but am finding it somewhat cumbersome.

Does anyone know a quick way to clear out the file with "Fabrics Used in This Project" when starting a new project?

It is a real chore to clear out one by one every fabric you've ever considered plus the ones for all the sample blocks you've used every time you start a new project!
