The small screen is your productivity bottleneck far more than the terminal itself. Change that and I’m sure you’ll notice a much larger productivity boost than a few seconds saved on cmd-tab or other hotkeys available (and there are hotkey improvement tools you can install that aren’t tied to a specific application).
I move around a lot and travel light, upgrading the small screen isn't really an option. I definitely agree there are probably countless ways I could further optimize my system, but switching to a more feature-rich shell app is a clear productivity upgrade, since it only took me a few minutes to setup the features I need (security concerns aside).
