Advancement Section (Wish List)

Adding a section (in the journal tab or in it's own tab) to manage the Advancement of the character (to record the purchases that was made with xp)

So, just wondering what you all are thinking this would look like? I'm open to suggestions, but want to make sure that I meet your desire/wishes if I can. Do you see this as a repeating section, or more of just a text area? What types of fields do you envision for this? I'd probably make this hidden by default, but allow it to be revealed via the Configuration window.
