There are often inputs that a player doesn't consider relevant when looking at a recipe tree, and it would be nice to be able to mark them as hidden (similar to how recipes are marked as default).

I'd imagine this would be something like a key binding one could press when hovering over the input (either in the recipe or possibly the recipe tree view). This would cause the input to not show up as a synthetic favorite and either be hidden or somehow specially marked in the recipe tree, and probably (at least by default), not shown in the list of base resources required.

Some examples of where this could be useful:

• When using Mekanism, it is common to setup multiple metallurgical infusers, and automatically stock the infusion material. Thus, it would be nice to ignore.
• When using GregTech, there are several machines that use a fluid as input to all their recipes (such as water or lubricant), that are setup to be stocked automatically (or use so little per craft that they can be refilled manually). It would be nice to be able to ignore those inputs.
• Also in GregTech, there are several recipes that use fluids that make sense to craft in bulk (such as rubber for coating wires, or glue and polyethylene for various assembler recipes) that it would be nice to be able to ignore.
• This might also be a way to handle tools and the like that are not consumed by recipes, but this would likely be more of a workaround. (See #124).

This would introduce a lot of complexity to the user in a way that's hard to both quantify and teach, but I understand the desire to solve this user facing issue.
