Not sure exactly how to explain it, or know if byond can do this already, but in my days of tampering with conquer onlines C# source, i came to realize it had a grouping method in the code so once you were done with that bit of code you could minimize it in a sense.
I was wondering if byond does have it or would consider adding it for making things look... neater.
for example with the c# code it would look something like
;End Case and everything between the ;Case and ;End case would get a + - drop box for minimizing or maximizing.
Definitely not the exact code on c# since i dont have a source to look at and my memory is fuzzy but hopefully you guys get the idea.
