At present, this mod exclusively adds support for using the + button in JEI and EMI to fill ME Interfaces, Export Buses, and Storage Buses, as well as their ExtendedAE versions. You can see it in action here!
The next planned feature will be adding support for ME Input Buses/Hatches from GregTech, but this may take me a while to implement and will only support GTM 8.0.0 and above.
It's unlikely that I'll port this mod to any other versions (MAYBE 1.21.1 if someone asks me nicely enough), but I will be working to get these changes merged into AE2 itself on 26.1 and above.
