Worked on the aseprite/aseprite repository to address a UI issue affecting the timeline editor. Focused on improving the alignment of underscore and strike-through decorations with layer names, the developer implemented a C++ solution that recalculates decoration positions based on text bounds. This adjustment resolved a longstanding misalignment problem, enhancing both visual consistency and usability during layer edits. The fix was regression tested to ensure no performance impact and maintained a seamless user experience. Leveraging skills in C++ and UI development, the work contributed to a more predictable and developer-friendly interface for users editing layers within the timeline UI.
