February 2025 monthly summary (tolgee/tolgee-platform) Key features delivered: - Implemented a dynamic language limit for the translations UI. The number of languages selectable in translations view is now configurable and enforced in the frontend, sourced from application properties to improve usability and prevent overwhelming selections. Major bugs fixed: - No major bugs reported or recorded for this period. Overall impact and accomplishments: - UX and productivity gains from a configurable, property-driven UI constraint that reduces cognitive load and potential misconfigurations in translations workflows. - Demonstrated end-to-end integration between backend configuration and frontend enforcement, enabling easier tuning without code changes. Technologies/skills demonstrated: - Frontend UI constraint enforcement, property-driven configuration, and feature flag-like behaviour via application properties. - Commit-focused delivery with traceable work item: 915b29fca128c3d162d1c8683430a97ee029ef17 (feat: Configurable selected languages limit (#2953)) Top achievements: - Dynamic language limit for translations UI shipped - Limit value wired to application properties for runtime configurability - Clear traceability to commit 915b29fca128c3d162d1c8683430a97ee029ef17 (#2953)
