Not sure if this totally makes sense or would even be possible or desired by many but,
Have the ability to route the stomps and effects blocks to be anywhere i.e. if you needed more stomps in front you could route individual x,mod,delay,reverb, to act as stomps in front and vice versa. Maybe you need the stomps to be post amp stack thus giving you 4 extra blocks for whatever. Or like the other way giving the ability to let's say, use the X and mod slot in front giving you 6 blocks in the front. A small extra menu or tick box with a dial could let you put anything anywhere. Hope this helps for what it's worth.
