What I read about Tabula Rasa was a mod that added 1 custom item and 1 custom block. That is not even compared to what CustomItems gives to us. That was why I asked why would InfinityRaider discontinue CustomItems when TR is relesead to 1.7.10. Or TR will be updated to a more complex mod?
Actually, TR can add 32k items and 16 blocks
Actually, it's N * 16 Blocks and M * 32k items.
Code is there; it's LGPLv3, but I'll have a release at some point. It works. Some people have been running it for a bit now.
