When you long-press and move a shortcut off the desktop (to the trash can), you are automatically sent to the UNINSTALL wizard. You can simply choose Cancel if you want to keep the app, or tap OK if you want to uninstall the app. At first, I was slightly annoyed and thought maybe this was a feature of that particular widget. Been then I've observed it happening on other widgets and apps. I think it's really just another cool feature of Home++ beta.
