Octopus Deploy 4.0 - Variable Editor Redesign

Octopus Deploy 4.0 introduces a redesigned variable editor built on a new UI framework using React and Material Design, offering a cohesive and user-friendly experience. Key enhancements include the grouping of variables with multiple values for different scopes, which streamlines the process of renaming and managing variables. The editor features an overflow menu for additional actions, a popup dialog for complex variable editing, and a description icon for annotating variables. Improved filtering options make it easier to manage variables, and keyboard navigation enhances user efficiency. Performance optimizations ensure the editor remains responsive, even with large variable sets, and feedback from users will guide future improvements.
