Adding Tabs at the top of the request pane

[animator]

Tell us about the task you want to perform and are unable to do so because the feature is not available This feature will be very similar to how we interact with files in VS Code via tabs. Whenever a user clicks on any request it opens in a new tab. It can have some indicator to show if any unsaved changes have been made to a request.
