Hello!
I am not sure if it is possible to move pages backwards to be honest, but I'll see if there is some workaround for it.
In regard to NPC tags, some people have expressed an interest in this as well. Originally, each NPC was supposed represent a "population" of multiple individuals. However, since people seem to want each one to be a separate entity, I have started to look into a possible expansion of the NPC system where each one will also have a randomly generated name. This is mostly in the planning stages at the moment and there is no exact date for implementation yet as I'm working on the system quite slowly and on the side while developing the main content of the game.
The farming area in Emerald Falls is not going to get bigger, however, there are some plans to add a possible cave with mine-able nodes. There will also be other houses later on in other areas of the game which will have their own farm-able land plots.
The only Skill which you can't get from a chest is Mining... I think I just forgot to add it in, so I'll add it for the next release.
