Widget drawer/tab alternative

[AC Question]

Hello,

I got a new car with Android 4.1.1 multimedia system. No Play Store, very limited settings menu, and only few apps. I managed to access the Play Store, which was hidden, through "rate me" button in one of the apps. From that point I was able to install and update anything, except from changing the stock launcher.

The launcher doesn't have Widget tab or drawer. However, there's a large time and date widget on the home screen, so widgets are enabled.

So, is there an app which can act as widget drawer, or app which can enable the widget drawer in some way?

Thanks,

Steve
