I was needing this today so I wanna +1 this. Would love to have a way to cancel a task/todo.
I know that Bear used to have completed todos form a strikethrough, and they removed that which I think it looks great now with a completed task being dimmed.
I wanted to add that for cancelled tasks only (should the feature be added) the strikethrough should make a return and also be dimmed.
That’s what I ended up doing. The only issue is that you still have an incomplete checkbox which can be confusing. Or you have a checkbox that’s checked but with strikethrough and can be mistaken as a task that was completed. I opted for the latter as it dims out the text.
Ah OK, i see. I am not a specialist in markdown standards but as far as i know all markdown languages just support two states. Though the op say something different
Another idea/workaround: Highlighting the the checked but cancelled task or moving it to another section manually? Or adding a special icon to it?
I know how frustrating it can be to hear that something would be easily possible but is forbidden by a standard
Maybe turn the checkbox into a list item and add a strikethrough? That’s my workaround because I use the @todo search filter often. It’s easy to switch between checkbox and list with ⌘ + T and ⌘ + L.
