Monthly summary for 2026-01: Focused on delivering scalable editor experiences and reducing API debt across two repositories. Key features delivered include a Textual Coder Editor overhaul in gtoolkit-coder with direct editorElement access, visibleText retrieval, and refined context menu integration, plus improved handling for large methods. Migrated Lepiter’s code editor to the new GtSourceCoderElement with initialization/UX refinements, font/layout application, and updated shortcut bindings, alongside more reliable local variable renaming. Addressed stability and consistency post-refactor with targeted fixes to examples and editor mode handling. API cleanup notes were incorporated to ease future maintenance. Overall impact: higher developer productivity, smoother editing experience for large codebases, and a clearer path for future enhancements. Technologies/skills demonstrated: GToolkit editor refactors, GtTextualCoderElement and GtSourceCoderElement usage, API modernization, UI/UX refinements, keyboard shortcut management, and Smalltalk-based development practices.
