Also, IdeaVim is just awful compared to Evil.

- Tracks the mode globally (rather than per editor), and treats mode-switching as an edit operation (so if you accidentally enter a read-only tab in insert mode then you need to switch to another tab, escape, and then go back to get your keybinds back.

- Doesn't bind escape in sidebar dialogs, so trying to exit insert mode in a terminal or commit dialog just defocuses the sidebar instead

- Still applies its other binds, so even falling back to CUA/IntelliJ keybinds doesn't work either!

- Makes no effort to integrate IntelliJ keybinds, all you get for conflicts is "would you like to lose the Vim or IntelliJ functionality that binds this key?"

The difference is stark when you compare it to something like Evil that actually values the user experience. (How's that for an irony?)
