Worked on improving the user interface of the MuseScore repository by addressing a specific issue in the Accidentals Palette. Focused on UI development and bug fixing using C++, the developer replaced the generic BRACKET icon with the more accurate BRACKET_PARENTHESES_SQUARE icon to ensure correct visual representation when users add brackets to accidentals. This targeted change enhanced UI consistency and reduced potential confusion, aligning the interface with established design specifications. The work demonstrated attention to detail in visual fidelity and user workflow, contributing to a more intuitive editing experience. The contribution was delivered as a single, well-scoped bug fix.
