Just had an idea today (for my calendar/reminder manager that I want to implement)
What do you think about having a widget to allow to slide trough different options.
I have in mind, one to slide trough dates, another one to slide/select hour/ ...
I would only display three options (previous, selected, next) but probably better if this can be configure.
I believe that this can open new fun perspective on what we can do with this touchbar.
