How to enable advanced mode/features in TSM when you initially chose "beginner" mode

[SteelBalls]

I just got trade skill master and I'm watching some guides on how to use it. When I first got it, I chose beginner mode but now I want to enable all the advanced features. How could I do this?

From the FAQ:

My Auctioning settings look different from a guide / friend / etc. I seem to be missing settings in my Auctioning groups.
You likely have advanced options hidden. You can show them by unchecking the "Hide Advanced Options" checkbox in the top "Options" page of the Auctioning Groups / Options part of the main TSM window (accessed by typing '/tsm' or clicking on the minimap icon).
