The number of unused points now shows on the tabs for ingredients and research. When allocating the points to machines it would be helpful to have the number of machines I have shown in the tree. I think a small number in the lower right corner of the machine’s icon (See Evaporator) would work or an option menu item to turn on an overlay to show the count on top of the icons (See Agglomerator).
I like to allocate points to upgrade ingredients based on the volume of usage. Clicking on each one and checking the usage for all companies does get tedious with the more ingredients there are and at times I forget which one had the highest count. I suggest adding a usage number on the ingredients to indicated the usage for the last 30 days.
