Thanks for all of the suggestions. The digital scale was actually added later in the development process and there is a setting in the menu to disable it. I just thought it may be a bit too hard without it. Also, if I am understanding you correctly, I believe you are suggesting a popup when you hover over a block that has been weighed already and it says how much it weighs. This is a pretty good idea, and I have an interesting twist on it in mind that I think would be a pretty engaging mechanic.
