If anyone is interested I've made some edits to the IC2 energy block textures (Batbox, MFE, MFSU, and all 3 transformers). I find I can no longer live without these texture modifications and wonder why the default textures are not as explicit.
The XCF has all the names on a layer which would make them easy to hide. The markers are on their own layer as well so they could be easily edited to be much smaller, like say small dots in different patterns. Personally I like the markings to be very bold.
