I've been working on datadriven item effects over the summer. Without being able to code, tetra addons have been stuck re-using item effects and abilities already available in base tetra. With this change addons will be able to add new types of effects in the same way as they add new materials and modules.
This might be a bit too technical for most, but I wanted to give you an update about what I'm working on. You can check out a preview of the docs over here: https://tetra.mickelus.se/wiki/1.20/tech/item-effects
