For instance, the TerminalView is not available on Windows. It would be great if I can configure Package Control to install TerminalView only on Linux and OS X.
I presume that you are syncing packages across machines?
If so, this is probably an enhancement that will need to be implemented.
@roycyt As a temporary fix try adding:
to the file Preferences (Windows).sublime-settings.
I tried your temporary fix and the result was the same. I don't think Sublime Text or Package Control will read this file: "Preferences (Windows).sublime-settings."
