Instead of having an `if` for the register command, I think it would look better to do something like
```
var showInOS = Strings.CMD_SHOW_IN_OS;
if (brackets.platform === "win") {
    showInOS = Strings.CMD_SHOW_IN_EXPLORER;
} else if (brackets.platform === "mac") {
    showInOS = Strings.CMD_SHOW_IN_FINDER;
}
```
Before the we register all the commands and then just call `CommandManager.register(showInOS, Commands.NAVIGATE_SHOW_IN_OS, handleShowInOS);`.

The same thing could be applied to the exit command.

An alternative could be to set a string in Strings.js, but not sure about that.
