Test Failure Explorer app lets you browse, search, page, and copy analysis for up to 20 test failures. The H3 Monitor and background Shell let runs continue after the turn ends, preserving output artifacts. Web Shell replies include a selection menu with Copy plain text and Copy Markdown actions that keep the chosen formatting. Task reminders alert users when tool approval or AskUserQuestion answers are needed, with configurable notifications and in-panel help. A new workspace file browser offers drag-and-drop uploads, read-only Excel previews, and quick access to file previews and agents.
