I'll just copy paste my initial post from Discord. Please excuse any weird formatting errors should they arise, it's a simple copy paste job (EDIT: Okay, it seems canny doesn't do indentations)

As a user, I would like to have the following functionality:

• a block that shows me all the To-Dos on a page. This would be the basic functionality

• Make it an Index Block and give us the ability to specify pages we want to scan for To-Do Items

• Also, the ability to specify a parent and auto include all child articles would be nice

• The ability to just show the whole project would also be nice

• Extra points if the block could show you on which page in which Element the ToDo was made

• Extra extra points if it takes you there if you click on it

• The block has the ability to toggle All/Completed/Open

• It automatically marks a To-Do Item Done in the page when I mark it Done in the To-Do Block
