I am using Picasso in my app.

First, I only use the format below:

```
Picasso.with(context)....into(imgView);

```

This way I assume I use Picasso as a singleton. Do I?

Second, I want to use `setIndicatorsEnabled`. However it cannot be added to the format above since it is not a static method. Is there any way to use this function in the format above?

Third, if I need to create a custom instance using `Picasso.Builder(...).build()` in order to use `setIndicatorsEnabled`, what is the best way to achieve singleton usage across the activities of the app?
