I’m not convinced this is necessary, given the calendar view’s grey circles in 3.0.

I think before something like this can be considered, the confirm view would first need to have dates shown. Currently the confirm view doesn’t show enough context to be able to confirm items without having already glanced at the timeline. If you went straight to a confirm view, without viewing the timeline of that day first, then you’d often be in the dark, because not even the date is visible on confirm view.

Basically confirm view would have to improve, with more context information, before something like this would be possible.

Right now, going to the calendar and then select each grey day is very slow. This of course might change with more optimizations in this part, but from a UI standpoint, a separate list with unconfirmed items (by week or month would be fine) would be extremely helpful.
