Unfortunately, as we said in our previous devlog, this is something inevitable following the implementation of the new UI. You should be able to skip all the text you've already read pretty quickly once you've started a new game! Really sorry for all that.
So, to answer quickly: we didn't implement this solution simply because I didn't know it was possible. The NeveN team doesn't have a dedicated coder at the moment and, although over time I've started to learn how to do more complex things, I'm still a beginner at it and it takes me a while to do anything that's a bit difficult. I've been working on this UI for over six months and, to be honest, once I got it working I didn't really dare change things too much for fear of crashing something that works, despite losing the saves. I may try to implement this solution for the next build though, see if it works.
