this is hardcoded..?

this is hardcoded..?

Yes it is. This defines the layout that will be used to parse the dateStr

func time.Parse(layout string, value string)

Here we are back to checking menu selectors in the handler code. What functionality is missing to be able to avoid this?

We can discuss this in the meeting, on how to use the lateral navigation indicator as this just prevents the navigation input from being processed
