If, say, I want to see what all can be in a dungeon chest, I would see this page:

This scrolls on its own, which means I can't get a clear list of what it has. Sure, I can hold shift to make it pause, but why do I have to? Why aren't there multiple pages of dungeon chest loot, literally every other recipe style? It's like if furnace recipes all cycled through whenever you wanted to look at one, and you couldn't choose which ones were visible.

The reason this is specifically annoying to me right now is that I want to find what spawns in dungeon chests that shoudn't, like IC2 ingots. Unfortunately, the only way to do that (without some kind of dumping mod) is to wait for it to refresh, hold shift, look for anything that shouldn't be there, bookmark it, then repeat.

This is true for basically all JER pages. There's a single page for Farmer trades, and it just randomly decides which trades to show instead of having multiple pages with all of them.
