Yeah, i've recently tested mods. And many parts of UI of workstations (Composter and Garden Workbench) are not compatible with SMX. Besides, composter don't even want to craft compost, (i don't know why)
I'd be glad to see this mod compatible with SMX UI once. And if you wanted to take a look at the screenshots or any additional information to solve it, i'd be glad to help u too.
