new widget for the touchbar: selector

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.

Interesting.. How do you think someone would set this up?

I did not think about the full details of it. I do not want to be too precise for fifafu.
but I would see a way to import a list (as json?) such that you have the option to display text or colored image.
and then some basic formatting options (size of the slider, icon for the central selector, ...)
