First, a big THANK YOU to steinio for continuing this mod.
I'm sure he will update this soon, but if you are as impatient as me, you can get this to work with 1.1.1 with just a few edits. NO GUARANTEES!
You will need to edit shortcuts.lua to change the 4 instances of
create-blueprint-item
to
spawn-item
and the 4 instances of
item_to_create
to
item_to_spawn
Then, edit selection-tools.lua to change the 4 instances of
flags {"not-stackable"},
to
flags = {'only-in-cursor', 'spawnable'}
Finally, you will need to edit the info.json so that the 'factorio_version' is '1.1' instead of '0.18'.
Obviously, make back-ups of everything before making any changes or loading a game. This is working for me, but again, no guarantees.
