Sorry, no, there's not a better way. I need to add this to the FAQ
real soon now. Here's the answer that I sent someone else a few months 
ago:

 Well, you can manually turn off inertia each time by typing "ui" in a
 window, or by using the Motion menu on the main panel. Sadly, it
 looks like we didn't ever define a GCL command to control this. But
 there's a total hack that you can use in such cases: the GCL command
 that simulates an ASCII keyboard event will provide the same effect
 as if you'd typed "u" then "i". You'd put this in your .geomview
 file:
  (rawevent 117 1 0 0 0) (rawevent 105 1 0 0 0)

 so that this happens every time you start up Geomview.

Glad you like it :)
