August 2025: Delivered targeted UI and reliability improvements across Survey Creator and Survey Library to boost user productivity, prevent data loss, and improve maintainability. Key updates include a manual Save action in the Survey Creator footer when auto-save is disabled, and a robust navigation flow in the Survey Library that waits for ongoing tasks before executing actions. UI stability fixes addressed inplace editor rendering, alignment of action buttons after removing Convert To Input Type, and toolbox item selection correctness, with updated tests. These efforts reduce user friction, improve reliability, and strengthen test coverage for edge cases. Tech focus: frontend UI enhancements, asynchronous task orchestration (taskManager.waitAndExecute), and test-driven validation.

January 2025 performance summary: Delivered API naming consolidation and deprecation strategy across survey-library and survey-creator to improve consistency and future compatibility. Implemented SurveyModel API renames (clearValueOnDisableItems -> clearDisabledChoices; onLoadChoicesFromServer -> onChoicesLoaded; onProcessTextValue -> onProcessDynamicText) with deprecation messaging and backward-compatibility updates to question_baseselect.ts. Enforced UI layout consistency and stability: set itemFlowDirection to 'row' for image pickers and added tests for default horizontal layout; fixed rendering for required indicators in matrix dropdowns with displayMode: "list" across Angular/React/Vue. Performed internal refactors and styling cleanup to modernize the design-system: SCSS cleanup for action bars, added sd-element class to HTML/Image questions, removed CreatorV2 flags, and simplified design mode logic. Expanded API renaming work in SurveyCreator to standardize property/event naming across core areas (Preview tab, maximum properties, undo/redo, auto-save, survey title, element operations, fastCopyQuestion, logic callbacks, and related getters/showers), and enabled V2 default options. Additional quality improvements include dark mode UI fixes (toolbar and color editor), matrix/inline editor fixes (panel borders, backspace behavior), and UI usability enhancements (collapse previous questions when expanding, default navigation and responsiveness settings, page interaction fixes) with updated test etalons and validation notes for future migrations.
