Add a checkbox to "To-do" creation which makes the to-do visible to only the creator.
This would be great for legal teams and security teams who may have to dos that are specific to their orgs but shouldn't be visible organization wide.
Thank you for your idea. This is currently possible today.
Any to-dos created without a linked record will only be visible to the creator and any assignees. So if you create a to-do where you are the only assignee it will be private to you. You can do this quickly by creating a to-do from the + menu on the right hand side of the menu.
