Mar 1, 2026March 2026 (2026-03) — Delivered targeted UX improvements in measurement mode, expanded palette/gradient tooling, and completed major modernization efforts across 3D Buildings and Kotlin migration. Key features include measurement-mode UX improvements (auto-centering on map tap, closing the context menu after adding a point, and hiding the My Location button when the context menu is visible), richer palette and gradient controls, and new terrain/gradient capabilities (slope palettes editing and plan offers). Code modernization efforts (Java to Kotlin, modularization of 3D Buildings) lay groundwork for faster feature delivery and better maintainability. Stability and reliability improvements across track filters, NPEs, rotation handling, and UI alignment/insets reduce crash risk and improve user trust. Technologies demonstrated include Kotlin migration, modular architecture, MVP/MVVM UI patterns, and comprehensive UX polish with clear business value.
