If you're using the #NoFilter book in a multiblock kitchen and you click on a missing ingredient in the left view (as per #260), there doesn't appear to be any way to actually craft that ingredient (as it's not immediately visible in the right pane) and there's no way to return to the previously viewed recipe, short of clicking something else in the right pane.

My suggestion is to add two things:

1. When you click on an ingredient in the left pane, also set the right pane to filter only on that ingredient (so that it's easy to find and click to craft).
2. If you press Backspace then it returns to the previously shown recipe for the left pane (similar to JEI), and also updates the right pane accordingly. You should be able to make multiple steps back, at least back to the original recipe that was shown when you first clicked an ingredient.

An alternate implementation of the first might be to add a "craft" button below the recipe without changing anything in the right pane.

If #150 were implemented as well, this would make it a lot easier to step through recipe chains where some additional ingredients need to be crafted first.

If #112 were implemented as well then it might make some of this unnecessary, but I still think it would be useful. (But I would love #112, especially for the regular filtered book.)

The backspace proposal to go back sounds good.

The problem with the ingredient crafting is that it's no longer locked to items you can craft using the kitchen (e.g. if you go far enough on bread you'll eventually get to hay bales, which don't exist in the right pane) - however, I could make it so it at least scrolls towards the item on the right if it exists there, allowing you to craft from thereon.
