The current stacker plugins are WildStacker and UltimateStacker. Both are outdated on cubedcraft (1.19) and don't work. So my suggestion is to either update WildStacker or add RoseStacker which seems to be a better alternative.
As in it groups multiple items into a single stack right? Paper does this by default
but isn't it limited to 64 though? paper just increases the merge radius of items i think
Ohh ye it’s limited to 64
Ye it just increases the merge radius
I’m not really sure what you plan on doing with it but for most situations I think having a cap of 64 in a single stack isn’t really an issue
im making a farming server so i think it could get pretty laggy with a lot of items in farms
