Well, it seems clear to me now, that if it
really doesn't mess things up, it would be a good move to expand this.
I think new players would appreciate it, people who already switched to named system would appreciate it, and even people who would have to make some rearrangements would appreciate it because having more slots per page is much more beneficial in the long run, regardless of adopting named pages or not. Especially, in a game with a lot of branches.
IMO, the pros outweigh the cons, particularly if it's done sooner than later.
