Thanks again for your feedback. Here’s our comment on your two questions
24 hour format
I’m not really sure what you mean. If you have a time field in ACF and you select the 24 hour format, you will see also see this on the overview, right? In our upcoming release, you can change the date format for your column so I think this is not a problem anymore in that version.
Flexible content type
I’m with you that the current info for the Flexible Content Field is not saying much and this info can be improved. The problem is that this field is so flexible that we did not get a better solution for determine a value for this field. For example we use this field for some of the website for our clients to make content blocks that can contain a lot of information. It would be a massive column if we display all possible fields for the different flexible content types. We could for example always show the first field of a content field, but maybe this is not relevant at all for some setups.
I like the new option for the repeater field where you can set the field that is shown when a repeater row is collapsed. If the flexible content field had this, we could use this field to extend the information but unfortunately the field does not have this feature.
Hopefully you understand that it quite a challenge to find a good implementation for the value of this field but if you have a good suggestion, I would love to hear it.
