FILE SIZE (TEST NETWORK)

I did not find it hard to scroll, as you can just click on any exa an it scrolls to its code automatically. You can then make them their own window so you can easily see all your EXAs code run at the same time without any scrolling regardless of file size.

It's not your bad, it's just me who is too lazy to do some visual works this time lol. My previous puzzle took me really much time and effort, so much that I think it definitely deserves good visual looks. This puzzle took me about only 10 minutes to make, making me feel that this is extremely simple and I should make my network simple too. Sorry I didn't know I would made you misunderstood.
For your idea of filling files with actual data: I actually already considered this when I was designing, but since these files are of size of many hundreds would it take horribly large space in the coding panel...? Note that the file content cannot be folded when the file is grabbed by an EXA (or at least I don't know it can), making it probably a nightmare to scroll if the solution involves multiple EXAs (including replicated ones).

Another nice puzzle with some very good options for optimization (I got i t down to 74/44/1).
Sorry for my comment on your other puzzle I might have pushed you to minimalism too hard.
Thought for improvement: use randomInt(1000,9999) or similar to fill the files with actual data. Or even something like random 4 letter words would feel more like real data.
