Non-Functional "Display" Options

At the bottom of the panel/drawer at the left are a pseudo-dropdown showing “Display:Normal” and a slider, neither of which is currently interactable.

In Pivotal Tracker, if I remember correctly, the slider controlled the amount of spacing between columns. I don’t remember what the dropdown controlled, or what the other options were. But having them as completely non-functional elements here is a distraction; I would suggest removing them for now, and adding them back if/when the variable-compactness feature they would control is implemented.
