I am not sure about dynamic recipe icons, is there a way to handle it? I mean not simply snap an ore icon.
You can! The icons property on entities, items, and recipes allow you to do things like layer icons on top of each other and make icons from existing sprites.
If you separated the little +1 and catalyst icons from their base images and then used the icons property you could dynamically generate icons for other mods' resources.
If you have specific mod compatibility request it is not a problem for me to add it, say which ones.
I think if you implement it right, it should be entirely possible to get basically every mod working with it, except for maybe Space Exploration (not sure how to handle its surface stuff yet, which is why I didn't do anything with ClaustOrephobic to accommodate it)
