It’s possible, but probably considered more later on when we are through some of the more popular requests/issues and some ideas here. There are just too many other things we want to get to with widgets and slightly paranoid of adding too many toggles too quickly for them!
@purple definitely a strong candidate for it. Just didn’t want to rush into sticking it there (as it was in beta) because there are some other possible future actions that may compete with this spot, like checking off the entire list, or sharing it more easily.
Meanwhile eventually we want to get to personalized gestures too, where you could customize that and other gestures with your actions of choice. But that’s obviously a pretty huge project, something we might eye for Clear 2.5 or even 3.0.
