Use existing response preview tab on subsequent requests

[TrevinAvery]

When I click send request, it opens up a tab to the side that shows the response. Sometimes this is not where I want the tab, so I move it tab around to better fit my screen. When I click send request again, it closes the original tab and opens a new one in the original location, off to the side. It would be ideal if it instead updated the existing tab that I have repositioned, retaining its new location.

How does one "vote" for a Github issue? :)
