it would be cool to have a mod that allows you to convert rotten flesh to leather by putting it inside a furnace or smoker.

There is already a Vanilla Tweaks datapack for this: https://vanillatweaks.net/share#kjFFlG

There is already a Vanilla Tweaks datapack for this...

there are many mods and datapacks that do this, but i would prefer a serilum mod.

I appreciate the new mod suggestion! I have added your idea to the list. I'm keeping track of all ideas on the Trello page and added the URL of this issue there.

In order to reduce the amount of open issues on this Github repository, I'll be closing this issue.

It definitely does not mean I am not interested and I'll post a comment here if/when the mod is released. This might take some time, as bug reports take priority. But I'll definitely be releasing more mods along the way.

Thank you very much for the suggestion!
