Replace the term "delete unique permissions" with "inherit permissions from parent"
We find that many users do not understand the term "delete unique permissions". As result, many sites with carefully constructed unique permissions have inadvertently inherited the parent permissions. This has caused lots of support questions (reinstalling the owners permissions) and rework for the site owners, while no change log, undo option or version history is available.
Replacing this term with "inherit permissions from parent" might make it easier for people to understand what they are doing.
(And trust me, this warning is all over our training materials and users still make this mistake)
