Improvements to Stack

[puzzledmonkey]

Would it be possible to implement 2 (backwards-compatible) improvements to the Stack field?

1. Ability to show on create/update forms. Of course it would just be readonly - using the exact same code as the detail page. There is already Heading that can do this, but Heading has completely different formatting and sometimes it's nice to display some text in the 'form format' with a heading on the left and the info on the right.
2. Ability for the 'lines' parameter when calling Stack::make('Name', lines) to be a callback that's evaluated to return the array of lines. This will allow a dynamic list of lines to be returned from a lazily-evaluated function (with a reference to the current resource) when needed.

Thanks for your time!
