Regarding the Windows Terminal settings interface, the default editor is VSCode if VSCode is installed. Given the mention of VSCode later in the article I'm surprised that VSCode was not installed on this user's machine prior to attempting to edit the Settings.

(Also yes, it is unintuitive that you may want to install VSCode first in order to edit Windows Terminal settings, but is it that much of a stretch that Microsoft would imagine early adopter power users to have VSCode lying around already on their machines? As you said, they are working on a "proper" UI for Settings still, but as a first "get it out the door MVP release", especially with all the under the hood work that took to get them there, it still seems a reasonable play.)
