I don’t mind the checkbox on the right at all, but I’d mind it even less if you could swipe them on a trackpad so that they not only look like the iOS widgets but behaved like them, too.
This would require an enhancement to iOS OmniFocus to allow for more than one action (Delete) upon swipe. e.g. Swipe to bring up options for drop, delete, done. (red X, trash can, green check)
