I’ve used these, and extended with even a couple more of my own, and I’ll post a little reference as to how I go about when adding more alternatives to this impressive list. But first I wanted to show two queries I use to collate my alternative checkboxes from all around my vault.
List all checkboxes of a given type
```dataview
TASK
WHERE status="?"
```
Where you can change the "?" to match whatever checkbox type you want to see.
List all checkboxes for a list of types
```dataview
TASK
WHERE contains(list(["?", "!", "I"]), status)
```
Which lists all checkboxes with question, important or ideas. The list can of course be changed to whatever you like it to report.
Another useful set, would be the list of those referring to task statuses, like in list(" ", "/", "x", "-", ">", "<"), where depending on what kind of list you want, you could remove those you deem uninteresting for a good status overview or similar.
