i think simple compress can do something like this for players having larger scales of building like Factorissimo.

I intentionally wanted to draw the line on just metals. Intermediates like circuits also include gears, sticks, cables, red and blue circuits etc... Icons are not procedurally generated but drawn too, so it would be much work for it.

For "not so simple compressing" i'd recommend omnicompress or boxing 2 which can deal with all types of items from all known and yet unknown mods

Also deadlock's stacking beltboxes works great with green circuits too.

i wanted one that allows stack size configuration, the beltbox one doesn't really allow you to configure the exact stacksize.
beltbox one for an example, assuming the stack size is 200, and a stack is 5, the actual stacksize of a stacked item would be 40.

i see your point on the arts tho.
