When using components for repeatable entries, there is currently no way to customize the display format of fields in places like the "entry title" or the post list.

Minimal example:

Create an "Events" content type with a title and a repeatable component. This component contains just one date field to enable a list of dates & times.

The default view for this entry list uses the entry's ID but can only show one active components at a time, making it impossible to see all event dates at a glance. If I change the "entry title" option in the view for the component to the Date field, I do get a list of dates. Unfortunately, it is shown as raw data, which is completely unusable for content editor (see screenshots attached)

I feel there is an opportunity to introduce a "Display format" option to all fields, that is used in repeatable components but also in the post list. Date fields need a date format option but also text fields would benefit from options like truncating text.

An inspiration could be Directus, which handles this very well.
