I see what you mean, but it’s not what I was looking for: I’d like to limit the list of Items shown to a Contributor to the Items they have been adding to the repository.
I have the feeling something similar was meant to be: if I do login as Contributor, and then from the dashboard I go to Items and click on Search for items, I will see a list of fields but not the one containing the Contributors name (something that I see if logged in as Admin); it seems like there was the idea that the Contributor would be limited only to their own Items. But this idea is then not implemented: if I choose any of the other fields, say Search by Collection, then all Items of that Collection will be shown, including the ones that particular Contributor haven’t contributed at all.
As said, the reason behind my idea is that, having several Contributors and hundreds of Items, it would make everyone’s work easier to have to deal only with their own Items.
Maybe one could just change the Quick filter, adding an extra “Only my own contributions” option; but that would prevent from using any other option, like “Featured” or “Private”. Besides, I am not sure whether that’s doable with a plugin. Or, add a checkbox, checked by default, that’s performing the same action…
I’d like to hear from you and others what do you think of this idea, and if they could give me a hint on how to start implementing it.
