Remove unused IntelliJ IDEA features?

Question

Is there any possibility to remove unused features from IntelliJ IDEA 14?

Purpose:

• better performance
• ease of use

Some examples for unused features:

• File > New Project... - Griffon, Flash
• File > Settings... > Editor > Code Style - ActionScript, CoffeeScript, Gherkin
• Tools > Capture Memory Snapshot

Answer 1

Choose Menu File \ Settings... or press Ctrl+Alt+S. Choose Plugins, disable unnecessary plugin:

Then press Apply, OK, restart IntelliJ IDEA to feeling the difference. That help decrement IntelliJ IDEA's start up time, and increment performance (like suggest code , operation faster etc.)
