I've had a lot of experience with updating mods that had fallen behind on updating, and this mod looks like it would be really useful if it were updated to the most recent versions of Minecraft. I don't know how much support you'll find for 1.7.10, 1.8, or 1.8.9, especially since Mumfrey switched the LiteLoader project to gradle starting with 1.8.9, but I can help update it to any of those later versions for liteloader if you'd like

I expect the hardest parts will be finding personal motivation and not wanting to backport features/fixes to 1.7.10. The mc18 branch has some early work from a few years ago, but since then it's always been "just have to finish that one thing first". There was a HTML export feature that got a tiny bit of initial development (but will probably join recipe docking in the "abandoned code; maybe someday" pile), then later playing a skyblock modpack (and creating an extension mod for recipe support) drove multithreading and some API refinement.

I think I'll settle for implementing a spinner while recipes load (the icon's already there, it just needs to be placed into the GUI and have theme XML support added), then finally abandon 1.7.10 development.
