Mafalda Dias focused on improving the editing experience in the MuseScore repository by addressing a bug that caused loss of symbol formatting during paste operations. She implemented a targeted fix in C++ that ensured the correct cursor was used and that modified symbol sizes were explicitly preserved when pasting, resolving a longstanding issue with text and symbol handling. By updating the edit text object to carry formatting through the paste and insertion pipeline, Mafalda reduced user friction and manual reformatting. Her work demonstrated strong skills in bug fixing, symbol formatting, and text editing, contributing to the long-term reliability of MuseScore.
