Topic category: Feature requests and ideas for MCreator
At present, the only way (that I am aware of) to name a mod is when you first start working on it. If I've been working on a particular mod for a bit and realize that I've misspelled the name or otherwise not kept with my naming convention, the only way to change is to delete completely remake the mod. If other mods depend on it (like a tab that uses an item for its icon), errors will be thrown at me. Depending on how many mods I have in my workspace that reference this deleted mod in some way, going through them all and changing them could become a tedious process.
Having been working in eclipse for a short while, one of the features I really like is that you can rename a class file and it automatically scans for and updates all instances of that class in the code. I think it would be very helpful for modders to have this feature in Mcreator someday.
