Just a small button to scroll to last seen episode

[GamerJagdish]

Describe your suggested feature

It would be hella useful if there was an button to instantly scroll to the last seen episode,
Why is it required?
Basically when an series have around a thousand episodes it gets hard to track which episode is downloaded and which is already seen so we can delete it from file manager.
Scrolling is not ideal for this scenario.
Another way to implement it is by giving a feature to show top/bottom 4-5 episode while we are using the filter.
Because when we use the filter we know the last seen episode number but we can't delete the episode on top of it because it's not in filter list.
