Aug 1, 2025August 2025 performance summary: Delivered progressive feature work and stability improvements across ChimeraX core UI, plotting, and data handling. Core feature progress includes Residue Template Generation Enhancements (ongoing template generation work), Rating Changes Overhaul (partial UI overhaul with a separate rating area), and Column Collation Support (partial implementation). Foundational work for advanced plotting via Plotting Infrastructure and Scalar Plots; refactored to share common components. UI and integration improvements include ViewDock toolbar button registration and scalar tab naming adjustments, along with related UI enhancements to the description area. Major bug fixes focused on stability and correctness: preventing multiple RMSD handler registrations, ensuring proper notifications after model removal, preserving pseudobonds save/restore, preventing unintended clearing of groups when merging sessions, and fixes to default column visibility. These efforts collectively improve reliability, user workflow efficiency, and data integrity." ,
