[Inkscape-devel] Icon Preview

I've honestly never checked the Icon Preview out before and decided to this morning. It appears to me that the dialog may be broken (or it may just be my not understanding it). Is it supposed to have the extra widgets that the swatches dialog has? I'm talking about the swatches selection list and that X button widgets. Also, it appears to be a blank dialog otherwise, but when you hover around it does button highlighting (and it looks like you click those buttons to get the preview). Am I missing something here?
