Just wondered if you can set the Legend to open automatically and where that might be done.
Also if I wanted to change the styling of text (URLs in the WAB, etc) where those changes would be made.
If you want the Legend Widget to be open automatically then you need to add the openAtStart property for the widget in the main config.json
Open side panel at start
If you are really meaning expand the Layer List Widget then look here:
Layer List: Expand Layers by Default
Change the style of text
