Hi Mona,
I have the same issue, and I have to say that having zero padding in an input field that is set to "View" mode is not desirable. It completely detracts from the typical layout of the rest of the form inputs.
Very often we adjust the mode of a certain input field depending on the value of another field. This means that while the user is completing a form, the field could be editable or not, depedending on a certain value. Typically, when the field is in View mode, we populate it with a value so the user can see what the value is, and that they cannot edit it.
It seems like a large amount of effort to make the entire input field visible only when you want to edit it, and replace it with a Label when you don't, or even worse, pad the value with a space and try remember to trim it before updating the source - which are things we are having to do to work around this.
Kind regards,
R
