Is there a way to remove the word references if I don't want them to be displayed and take up space?
@rohitkrishna094 you can achieve this by set the setting rest-client.enableCustomVariableReferencesCodeLens to false
Thanks for your response. btw where can I find all these settings that I can change? Is there a doc somewhere? Thanks
