@wezm @Raspberry_Pi I would guess the reason for that is just a lack of time spent on UX review and refinement. They slapped a default combo box on there and assumed the Framework (GTK?) would take care of making the UX reasonable, when it would have only taken a few more hours to make it a listbox and add a search field. Which is just bad.

(Additionally, the priority on this interface may have been low as it may have been expected that most users would use the sd card preconfigurator instead)
