Welcome to the forums!
This has indeed been a pet hatred of mine for a few years. I proposed
a similar solution a while back, and also a way of
cycling through the savepoints. They were received rather well so hopefully a solution will be implemented.
Interestingly, I viewed this board with the intent of posting a new feature request linked to hitting Xs and avoiding the "
Oops, I hit 'r' (thinking I'd previously hit an X) and now I have to start the whole room again"
syndrome.
As it's a similar request to yours, I hope you'll forgive me if I post it here rather than create a new thread. It would also be handy to have all these requests in one place.
My request would be to highlight the last X hit so that the player can tell visually what whould happen if R was hit. This would be well in keeping with the DROD idea of hiding nothing from the player.
