Janek worked on enhancing Polish localization coverage in the truenas/webui repository, focusing on expanding and refining translations for the storage and jobs sections of the user interface. Using JSON to manage language resources, Janek applied internationalization and localization best practices to ensure consistency and accuracy across UI strings. The work addressed gaps in Polish language support, aligning translations with established localization standards to improve usability for Polish-speaking users. Over the course of a month, Janek delivered targeted updates through multiple commits, resulting in improved translation quality and preparing the interface for a broader rollout to the Polish user base.
