Simple fix to get this mod working in Factorio 1.1:

1) Change the value of "factorio_version" in info.lua to "1.1":
"factorio_version": "1.1",

2) Edit line 1 of control.lua:
replace
require "mod-gui"
with
local mod_gui = require("mod-gui")

3) In line 8 delete
, style="icon_button"

The mod should work just fine.

I had actually hoped that someone else would republish it, which unfortunately did not happen.
Thanks for the investigation, saved me some time.

I have merged the functionality into a new mod: Crafting Tools

I didn't republish it because I didn't know if it was legal in terms of the MIT licence.
