@meandmy10 Ok here’s a little more on what I was thinking.
Here’s a picture. Basically the amount of compounds is displayed by a bar that can fill and empty inside the box. It goes green if it’s in the right range, amber if it’s outside this and red if it touches the ends (it could even go deeper amber as it gets towards the edge). The number of organelles that can do the process is the number of lines in the arrow. So there are 3 that can turn glucose into pyruvate (so 3 cytoplasm) and 1 that makes Fatty Acid. You can control the process by clicking on the link. You can see the process to make fatty acid is off but the process to use it is on. This is a good idea because the level is high.
Anyway the CPA system will handle all this automatically (turning processes on and off when compounds are needed / abundant) but this would let the player have control too. It would also make it easy to see which compounds are low. Any compound box that is clicked on gets added to the quick menu which is always visible at the bottom of the screen.
It’s just an idea. Take it or leave it I really don’t mind.
