Would it be possible to add a GTCE cables compatibility? For now the only option would be an RF channel (FE support will be added soon), but it forces ppl to change EU->FE->EU. Ofc it's not THAT big of a deal, but if you were able to make it compatible that'd be great

GregTech: Community Edition... So if the mod im talking abt already USES forge caps it’ll just work fine on its own, w/o you even making a compat? Great to hear, thanks

Yupp, that's exactly right.
All sided(!) forge capabilities are supported out of the box!
You are welcome! Feel free to refer them other mod authors to me should any issues arise.

There is no and will never be any custom compatibility implementations for other mods.

Please ask the mod authors to switch to a Forge Capability based system and it will automatically work out of the box.

Edit: A few more notes:

• I have no clue what GTCE even is.
• It makes no sense for me to add compatibility for all the other mods, when all the other mods could just make their mods compatible themselves very easily (it's not even CM specific, but a Forge thing!).
• I got burned out from the 1.7.10 version because of custom compatibility implementations and dropped compact machines development for almost 2 years. Only the advent of Forge Capabilities (which is what tunnels are based on) made me reconsider.
