Add new array elements at the top

[lordrip]

Please describe the feature that you want to propose

When adding a new array element, for instance, a new header in the setHeaders processor, it would be better to place the newly created header field at the top.

This needs to be tackled at https://github.com/KaotoIO/uniforms-patternfly side.

Here's where the new item gets concatenated:

I do not understand why adding at the top. I usually expect that new elements in array are added at the end. Can you clarify in which case it is better to add it at the top/beginning?

[lordrip]

Let's say we have the following structure:

Title | Add button

• Item no. 1
• Item no. 2
• Item no. 3

When adding a new element, if it appears at the end, this means scrolling down and up to create a new item, configuring it and then going to the top to add a new one. For instance with setHeaders EIP

I would expect a scroll bar for the list of item itself, so that the title and add button are always visible

Another alternative could be to have an "Add new" button at the bottom of the newly created element.
