It would be a great improvement and, as far as I know, there are no other WP plugins with this feature implemented.
I see it working as follows:
– Every new from a feed would have two states: Validated – Not validated.
– The “control panel” would have two lists containing Validated and Not validated news as list items. Each new item has a checkBox or button to change its state.
– Only Validated news are displayed in the site.
I think it is a great feature, as it gives you control over feed’s content displayed in your site.
It would be great if you could implement it. Thank you.
