During June 2025, Caio Avidal focused on UI development and maintenance for the mehah/otclient repository, addressing a specific issue in the Client Options interface. He corrected a typographical error in the 'Show Expiry In Inventory' label, ensuring the UI text accurately described its functionality and reducing the risk of user misconfiguration. The fix was implemented using OTUI, with careful attention to UI consistency and clarity. Caio kept the change minimal and isolated to the configuration UI, supporting easy rollback if necessary. His work emphasized traceability, with a dedicated commit, and demonstrated a methodical approach to UI polish and stability.
