Brilliant idea. So nice to not run out of belts and inserters when you're setting up your factory.

Some feedback:
In version 1.1.0 it seems like stack size is either 0, 0.5 or 1.0. That's quite large jumps. How about increasing/decreasing by 0.1 or 0.2 instead?
Mod crash if you start in sandbox mode, enable cheat mode, build one inserter and then filter that inserter in the quickbar. Here's the error message:
Error while running event on_tick (ID 0)
No character.
stack traceback:
HandyHands/control.lua:42: in function <HandyHands/control.lua:17>

Thanks!

The crash is fixed in 1.1.2

Didn't read your post before I released it (No notifications at this forum, that's why I recommend the homepage/thread at the factorio forums). I try to check up on this forum too but it's hard to see which threads have unread messages and I have to check each mod forum individually, and then each thread in each forum individually.

The home thread also has a discussion on autocraft amounts. From that thread my last qonclusion is that individual settings for items will likely be in absolute amounts (to work with stack size changing mods too) with smaller increments while the default will be in stacks and have slightly more size options <1.

Thought I'd let you know: I mentioned HandyHands and Auto Research to Arumba. He didn't mention Auto Research in his latest video, but Handy Hands got a fair bit of coverage: https://www.youtube.com/watch?v=Tkj44MEbyZM

I was watching that series earlier but having them stop and craft stuff just before they needed it was killing some of my enjoyment of it. Now I can follow it again. And with double enjoyment. Instead of watching them pause because they forgot to craft I get to see my mod in action, which is pleasant ;}

Thanks canidae! The purpose of this mod has now been fulfilled!
