What Developers Are Saying

★★★★★

“Five stars because the core is good, and the development is active and genuinely shaped by user requests on GitHub. The author is responsive and ships improvements quickly. So despite the plugin still being young and missing some features, it’s heading in a great direction.”

Jon Lauridsen — JetBrains Marketplace
