Could you add 1x1 3-digit display? Large numbers look more natural when separated by three digits:
1 23 45 67 89 -> 123 456 789
I have made a visualization of it, looks good to me: https://imgur.com/a/N1gXgnz

I agree, good suggestion

I agree, good suggestion

I'm waiting for it too

Guys is it possible to somehow use it like this https://i.imgur.com/jiClRSs.jpg ?
Maybe even without the Alpha tubes and connecting the input to the first of each tube row and subtracting -999 and -9999 accordingly https://i.imgur.com/fqpVmVU.jpg.

I spent the last 2 hours trying to set it up but i just can't figure it out...
