Do you know this situation when you have marked some articles as read or removed their star, maybe by accident, and would like to find them again or undo your actions?
Well now in #FreshRSS (rolling release `edge`), it is possible to sort articles on the last user modification. There is even a new search operator, for instance `userdate:PT1H` for showing only the user actions of the past hour.
And yes, this also works when actions were performed from a mobile app.
