The Craft Manager menu (the one that replaces the stock "load craft" menu in VAB/SPH) does not obey KSP's UI Scaling setting. The attached screenshot shows KSP running at 4k (3840x2160), with UI scale set to 200%. All UI elements should take up the same amount of screen space as they would at 1920x1080 with scaling at 100%. Everything else is correct, but the Craft Manager menu is nigh-unusably tiny.
