True (but then again we don't change the format usually) . the --version is primarily meant for debugging purposes.

We could add something like '--versionnumber" that'll just print the number in format major.minor.patch.

This should be fixed actually in the master branch of the IFW (requires Qt 5 though). Here we print directly to the console if one's attached.
