So far i've been coding blindly just checking documentations whenever I needed to know something.
Using the Python plugin for IntelliJ, adding the spigot/paper api jars in the libraries will give you some level of intellisense but doing the same for the PyPlugins jar shows slightly different results (besides the fact that you need to remove the imports as they get injected by default) as for example PyEventHandler when importing would be PythonEventHandler and so on.

Reason for this question is, I'm trying to create a streamlined process where anyone can write fast Minecraft python plugins with as much intellisense help as possible. This would give newer newer devs more of a reason to pick this over Skript/Denizen for example
