Currently in our application we have tables of information that give you some of the most important data and them we have a view more link that pops open a modal dialog and gives the user all of the information for that row. This is also where we are placing the delete button for that row. The reason for storing the delete button in the modal is because the data is very important and we don't want the delete to be easily accessible.
The problem that I am having is I can not determine which location in the modal that would be the most usable for our users. I have come up with some of the different options that we have gone through and was hoping people could give me more of a professional opinion.
Option 1 is what we have at the moment, just a simple trash can next to the title in the modal (trash can is much smaller but this is as small as balsamiq will let me make it).
Option 2: Delete button in the bottom left corner of the modal.
Option 3: Delete text in the bottom left corner.
Option 4: Delete text in the header next to the title,
Option 5: Delete button would only be available in the edit mode and would appear on the left side of the footer.
