It's really hard for me to keep track of what is properly set to be a Placeholder Account or not. Yes, I can make the checked box column, but that's EDITABLE so I could easily screw that up.

It would be great to have that column be LOCKED or have a separate icon to denote the account is a Placeholder, so that I don't accidentally change one that I don't want to. Then I could just right-click the column to change if the account is a Placeholder or not.
