Annoying change to the app switcher function

With the latest update, the function to switch between applications (in German UI it's "Anwendung wechseln") was modified. Before, I could instantly switch between the currently and last used apps with a click on the thumb button. It was extremely handy and efficient – great alternative to ALT + TAB all the time.

Now, the switch doesn't occur instantly. Instead, an overview of all apps is displayed for about 2s. The benefit is that I can select any other app than the one I used last. The problem is that I cannot integrate app switching in my smooth workflow any more, as I won't wait that long for most back-and-fourth tasks. So I'm back to ALT + TAB instead...

I would appreciate if you implemented an alternative to "switch apps" that explicitely includes "show overview of active apps".

Cheers
