JetBrains has introduced the Islands theme as the default interface for its IDEs starting with version 2025.3, aiming to provide a visually softer and more cohesive environment that enhances focus and comfort for developers. This update features a clean, uncluttered layout with rounded corners and balanced spacing, making the user interface easier on the eyes, along with more distinct tool window borders that facilitate workspace customization. The theme also improves tab recognition for quicker navigation and organizes the interface to clearly separate working areas, which helps maintain focus. This design reflects feedback from daily users and aligns with contemporary design trends in macOS and Windows 11, ultimately supporting developers in staying productive and focused on coding tasks.
