Idea of new button is very good.
I could only tell form my point of view:
- pure box for normal behaviour
The disc sign was very intuitive for me.
- green tick for "prefer stock here"
A tick has for me the meaning: "Put wares here" (normal behavior). The green up arrow was good.
- red cross for "don't put wares here"
That is like fraangs suggestion
- red arrow to the right for "get rid of stocks"
Arrow to the right is much better than arrow to the bottom. fraangs decision is great plus. I think red colored button would also be better.
I am thinking about the cube. I think this should be a generic placeholder for each type of ware? If so, it is not optimal to show this on the buttons. Reason: We should think about what function those buttons have:
- They are related to the choosen warehouse
- They do something with wares which are stored in this (the choosen) warehouse
Wares are choosen at the top of the window, the buttons at the bottom make actions related to this (!) warehouse. So my suggestion (if there is enough space) is to use an icon similar to the second in last row (a stylized building). The arrows and crosses could be adjusted to the door of this icon. As said: If there is enough space
We should also consider people whose eyes do not work as good as eyes from younger people (or are colorblind). F.e. the red arrow do not contrast to the wooden background. A higher contrast would be appreciated
