Suppose I have a settings screen where I have a table with a bunch of rows with checkboxes. For example the default settings are:
| Name | Setting | | A | on | | B | off |
Then the user comes and toggles the setting A
| Name | Setting | | A | off | | B | off |
What's a good way to tell the user that the setting A is now different from default? Maybe some background color that intuitively conveys the message?
