Probably won't be able to work on this more today, so it's time to consider this day 1 of &vireac. So far it's just parsing a copy/paste of its own assembly code from msvc into a bunch of colored circles, but all the different instructions are distinguishable, and I can scroll through them easily. Step 1 is complete.
Step 2 will be grouping them up based on the c++ code that produced them, and trying to make them visually distinct by shape rather than color.
