In January 2026, Catreap developed a customizable Sandbox View for the sandboxie-plus/Sandboxie repository, focusing on enhancing user experience and workflow efficiency. Using C++, Qt, and UI development skills, Catreap implemented features that allow users to sort columns according to their preferences and ensured that these sorting states are preserved across sessions. The technical approach addressed a specific instability bug related to switching sorting modes, resulting in a more reliable and predictable navigation experience within the sandbox interface. The work demonstrated a targeted, user-centric improvement to the UI, with depth in both feature implementation and attention to persistent user settings.
