I know that's not the primary use or intended behavior of NVDA, but as a developer it would be amazing to be able to limit NVDA readout to a single window/application.
In its current state I'm forced to close and relaunch NVDA every time I switch between browser and VSCode to make some rapid changes and test.
Or maybe someone has an idea on how to efficiently deal with Screenreader testing in real-time while developing?
