Theme insanity

Trying to build a new theme has, at best, been frustrating.
But this is just insane… maybe I’m missing something, but does the xml element

seem like a logical name for the UI element indicated by my ‘X’ below?
This is the popup you get when you right click on the toolbar and select “Customize”.



I’m about to give up completely on the theme creation and general customizing of this program. Whoever is responsible for the design of this functionality, well, let’s just say I’m not impressed. And clearly the company isn’t interested in this aspect of a commercial application. I cannot even fathom how any software professional would allow stuff like this to make it’s way into a production release.
