Counting ticked checked boxes

Firstly, I have created a column with the Column Type of Checkbox and I want to have a summary but the only options are None, State, Hidden.

I want to have a count of the ticked rows. If I changed the column type to Number then I could do this but I would by necessity need to use 1 to represent a tick and 0 to represent an unticked. The visual appearance of tickboxes is much better than seeing 1 and 0s.

So how do I do this? Or would this be a feature request?
