I need to do some major surgery on a user account that has somehow sustained configuration damage to the point window decorations are gone, some apps don't listen to the keyboard, etc etc.

I run xfce4 sessions. There's a panel on the top of the screen that has applications that I put there once upon a time. I know how to do that, sort of. But I don't remember the details of what I specified. And I'm unaware of an app for the panel that's like the menu editor that lets you see and manipulate an item that's already there.

I want to do that because I want to re-do this stuff in a different account. Or possibly do a dotfile transplant on this account and re-edit to include the stuff I'm used to.
