Woah, that's cute sounds, great piles and algorithmathics! Ah, like in times of Colobot programming!
Ohh, I play 5 hours in first try and hardly make stable Forestry automation. Hm, still without tools remaking.
==Suggest==
Its quite hard to manipulate things in inventory for work steps. Especially tools check in the middle of harvesting.
Need to use number buttons for slots and place stuff to inventory slots directly.
...Or I just simply add one worker especially for log transportation and axe guy cut until his hands is empty (then take fresh axe), so no more axe-logs inventory messing.
Sometimes need Copy and Repeat of selected lines.
==Bugs==
Times repeat over Times repeat is infinite cycle.
Same with Full hands over Full inventory repeat.
Ah, already.
Find nearby Log after cutting tree take most far away Log.
Same with Tree Seeds.
