As I have seen many people say on youtube, and irl. Covers for cables would be amazing.
Much like the covers BC have developed, or say Eloraam, they would come in alot of handy when trying to hide your cables. As we all know, cables all over your house looks ugly, not because of the texture, but because of the amount you have, and how they get trailed through your home.
For example, If IC2 devs were to work with Eloraam, and say; make her covers compatable with IC2 cables so they worked (Not creative a small block on top of the cable) this would greatly improve asthetics, and also make alot of people not have to make huge alternate roots to make their cables invisible. This would same time, space and even cables (As we dont have to make complicated systems to hide them)
This idea is pretty out there, as we all know IC2 devs and Eloraam are all very busy with their mods adding cool new stuff for us; the consumers of their mods; to use, but I see this idea crop up alot, and whether it be added or not, it would still be a great addition to the mod.
