The best productivity plugin for JetBrains IDEs

I work as a professional web developer and the IDE I use is JetBrains Rider. It has loads of great features, but can also be extended using plugins.

My absolute favourite plugin is Key Promoter X. It helps you become a more efficient user of the IDE by helping you find and create keyboard shortcuts for the actions you frequently take.

Any time you perform an action with the mouse which you could have done via a keyboard shortcut, it will inform you what keyboard shortcut you could have used. (You can suppress these for things where you don't want to use the keyboard or already know the shortcut.) If there is no keyboard shortcut currently set up, it will help you set one up without you needing to wade through the full keymap in your IDE settings.
