Discussion 5 is relevant background to these suggestions. The suggestions are to have project level config options for the following:

• Font size.
• Line Height.
• Maximum widths for the left, middle and right panes. In particular, it would be preferable to be able to configure the middle pane to take up more of the browser width, if available, on larger screens.
• Minimum widths for the left and right panes - to tailor when they disappear because of lack of available width.
• Minimum content widths for the left and right panes - to tailor when horizontal scroll bars kick in because of deep hierarchies or long titles on content.

I may not have worded the suggestions in a way that matches the terms used in your implementation. They are not intended as the exact settings used. Its more an allowance for a general direction of suggested layout configuration. The general direction of these suggestions is to retain whatever the opinionated stance that Retype takes with layout/design but provide some configuration to control the compactness or density of the information content that is displayed. Some content is better suited to a higher density of text and some is not - depending on the intended audience and purpose. Note that the beta API functionality is an area that I think would benefit from much higher density of textual content.
