Francisco José Neves contributed to the FreeCAD/FreeCAD repository by addressing a user interface stability issue in the Advanced Settings dialog. He focused on resolving a visual glitch where the Animation Curve Type label would shift position after a selection, which could confuse users and increase support overhead. Using C++ and applying his skills in GUI development and bug fixing, Francisco identified and removed a problematic line in DlgSettingsAdvanced.cpp. This targeted change improved the reliability and consistency of the Preferences > Advanced Settings UI. The work was concise in scope, demonstrating careful attention to user experience and codebase stability within a short timeframe.
