The previous version of the debugger keeps all the requests open when changing tabs in the browser. The current version shows only the requests for the active tab.
This creates extra steps in the workflow when working between two or more tabs and the debugger window. This is often required when validating variables in an Adobe Analytics workspace while testing a page. Leaving the tab also collapses the request so it has to be re-opened and then scrolled to the right to see the current hit.
It would be better if the request would stay open, even when the active tab is changed. It would also be better if the focus remained on the most recent hit, rather than adding them outside the window so that they have to be scrolled to.
