Previewer: track order change of cards

[mhallal1]

In the simple previewer example of the vignette, if you add only plots or tables, you will have them all listed in the previewer.
If you try, to move one card up or down, it does get moved but you wouldn't notice it unless you check the content as the UI stays the same. Is it possible to make this more obvious when changing the order of cards? For example the card physically moves or a notification pops up if not?

That is why I introduce the Card name, in Your case you added only one module.
I like the idea to make it even more clear.

We can add some CSS transition animations to it so it is more noticeable.

Ideally, we create a widget for this and abandon the current R solution.

Do you have any suggestions on how we can improve the user experience beyond the current feature of being able to edit card names during creation, which can help ensure that each card is uniquely named?

Thanks for tagging me.
Thinking about how when we download files more than once, the duplicated files will be automatically renamed with a sequential index added as suffix. I'm thinking to apply the same mechanism as the default card name, so if user adds more than one card from the same module, they would just get [1] [2] [3] attached to the end.
Allowing editable card name is already another good mechanism - perhaps add some validation/checks to prevent users giving two different cards the same name?
