As a widget I get author information, site information,and date.
With the shortcode I cannot call author, or date, or site information.
It appears the functionality is already there just needs to be added to the widget box.
Would also love it if you can add specific site information to each post display. So if the 1st post came from site 5 and the 2nd post came from site 200, the list items that are now used to hold each individual post could be labeled <li class="site-5"> and <li class="site-200"> respectively. I could then style based on my sub-sites brand rather than having all posts look the same.
My last request would be Pagination.
