would be awesome if we could see what harvesters produce in REI, similar to what other mods with "void miners" (environmental tech, industrial foregoing, gregtech, modern industrialization, etc) display.
(what modern industrialization has, essentially just gregtech)

things like $ore only go so far, especially when other mods/items that show up in a $ore search, dont get "harvested".
(what $ore shows me in my lil modpack, is far more than what the harvester mines... i could configure it to obtain these, but i dont want it harvesting things like.. slime blocks, or forest green dye.)

Hi, I just realized I hadn't responded to this. Sorry about that.
Anyway, I think someone asked for JEI support at some point and I said I'd like to add it but couldn't at the time because I didn't know how (I had an idea of it but not enough to actually try) and that it might end up being inconsistent because the harvesters determine their outputs dynamically upon loading. I might look into it again.
