MATLAB Bode plot units

Sometimes I want Bode plots with frequency in Hz rather than rad/s, or a magnitude in absolute units rather than dB. I've been using workarounds like calling bode with output arguments and plotting it myself, or frequency-shifting the transfer function (for frequency in Hz).

But it turns out you can change it! Call ltiview, and you can use the GUI to change the default axis settings (File -> Toolbox Preferences).
