I really love what the mod does and I was looking for something like this for a while but it doesn't seem to work on some items like storage tanks, train carriages, etc. Is this something you could also add?
adding a "storage-tank" entry in data-fixes.lua in the machine_types list will fix this for the storage tank. I wasn't able to get it work for "cargo-wagon" and "fluid-wagon" though. Any help would be appreciated.
