The filter is a nice addition, but even though it's not enough, cause some routes are quite similar and sometimes people save half way through choices to try several different outcomes and just those 4 categories don't cut it. It will be much easier for the players to keep track of their paths if the saves stay in order and specially if you can name them. In my honest opinion I think
TTrick should make something about this in the next update, cause this is a great game, but this issue is extremely annoying for anyone who wants to try different paths and outcomes.
