Allow to access historical replies for a depth of a year for subscribed users
As hiding criterias tend to change over time (eg global grey-list of unwanted commenters to hide), I wish my app would be able to retroactively access (and hide/unhide) historical replies to historical tweets of subscribed users with a depth of eg at least a year from now.
At least, to access the list of replies my app had previously hidden.

Thanks for the feedback! This is not currently on our roadmap, but keeping track of the replies that have been hidden by your app should be fairly straightforward to do on your end. It would be helpful if you could give us additional insight into why this feature is important for you and tell us more about your use case.
