Feb 1, 2025February 2025 (nm-self-learning) delivered targeted improvements to the editor UX and selection flows in the teaching module, improving authoring efficiency and admin controls. Key gains include Lesson Editor UX and Permissions Enhancements—refactor of UI structure, tab management, and access controls for admins and authors, supported by fixes for markdown editing save/close and course-related learning unit creation (commits 5d6a2653ca2b53cb4928368c6adc04142cf55ae6 and f1b3c7b53d9cce28b84d70bd567982d028fc6413). Additionally, the DropDownDialog selection bug was fixed to ensure selected authors/learning units/subjects close the dialog and are passed correctly (commit e569e311217926eb7af77e4338ccaab8793240bc). These changes reduce editing friction, improve data integrity, and strengthen governance around publishing content. Technologies demonstrated include frontend refactoring, permission checks integration, and robust UI bug fixes contributing to faster time-to-publish and fewer support tickets.
