Worked on enhancing Linux file explorer integration for the bambulab/BambuStudio repository, focusing on improving the user experience when opening directories from the file picker. Developed a feature in C++ that validates selected paths, distinguishes between files and directories, and adjusts navigation to ensure the correct directory opens, aligning Linux behavior with Windows and macOS. This update addressed Linux-specific edge cases, particularly around the Open Containing Folder functionality, and reduced user confusion related to file navigation. Demonstrated expertise in desktop application development and file system handling, with clear traceability through commit documentation and references to related issues and fixes.
