Coming from the FeedDemon camp now that it is unsupported.
I wold love to have a back button / ability to go back to the previously read item. At times I read/skim too quickly and want to go back to the previous or past news item. But if my short term memory doesn't remember which feed it came from, I won't be able to find it again.
In the plans, but so far we do not know how to do it: https://code.google.com/p/quite-rss/issues/detail?id=299
A "back"-button is a nice idea.
What about having an additional field "previous" in table news where you store the id of the previously read news?
If you press the new "back" -button you always know which news to go to. That would solve the global problem.
If you want to do it by feed you can have a similar field in table feels. So you can go back to the previously read news within a feed.
