Suggestion: set Play Store as the installer app for root install

Some apps don't work if they're set as installed from any source besides the Play Store. Using the -i option for pm install you can set the installer package name (I don't think there's a similar way to do it with Intents, so it would probably be limited to root mode). This way those apps will work. I'm not sure if it would work on devices without Play Store installed or not, but it looks like you can set the installer package to anything, even if said package isn't installed, so it might.
