Add cursor/keyboard functionality in response section (& bring back environment edge status)

The title pretty much says it all, but I'd like to have the ability to select & copy text in the response area by having & using a cursor. I'm a keyboard shortcut kinda guy, so that would be a productive feature for me for sure. 🙂

The 2nd thing I'd like to request is bringing back the option to place the environment status highlighter to various edges of the app/window. Having a tiny dot in the upper left corner is not apparent for me. Personally, I liked having the right edge of the requests sidebar with the color/status highlighter.
