Some items allow a 1 or 0, and some must be ‘true’ or ‘false’. Would it be possible to have them all one way or the other?

elementPosition : uses “0” or “1”  
useDefaultViewWidth uses “true or flase” will only accept “true” or “false”

`elementPosition.grow` and `elementPosition.shrink` define the proportional growth and shrink of each instanced View based on the number of instanced Views, and accepts values between (and including) 0 and 1. This is NOT a boolean representation, it’s a numeric proportion, so no, we won’t be changing it from a numeric value.

`useDefaultViewWidth` accepts `true` or `false`, because it is a boolean value.

If you see a property on a component and it has a number value, it’s because the value is numeric. I can think of no property where we represent a boolean value with a numeric equivalent.
