Serious UI Design Flaw: Preventing the deletion of custom fields/forms

[#1]

I recently deleted custom fields that I was trying to export because once fields are selected, the Export button slides over and a Delete button pops into its place. I was distracted and when I looked back at the screen I saw to my horror the "Are you sure . . ." message disappearing.

Oddly, WF built in a device that does not allow Sections that are multi-selected to be deleted—but you are able to delete every single custom field in your instance with two clicks.

Preventing this from happening seems like a fairly easy fix:

• Default the "Are you sure you want to permanently delete this field and all associated data?" message to "No", not "Yes".
• Put the Delete action in a "More" dropdown, like it is with user accounts
• At the very least, put the Delete button to the right of the screen or to the right of Export. Don't move Export over!
