It may be possible to categorize functions and fields by reading this joined.srg file https://raw.githubusercontent.com/MinecraftForge/FML/master/conf/joined.srg
How about importing from the latest csv file on github https://github.com/MinecraftForge/FML/tree/master/conf fields.csv, methods.csv and params.csv
Also would it be possible to use the website to update the actual names? Like connect to MCP Bot automatically or something.
