- **Zip files**: double-click one to see what is inside and open its files, **Extract to...** unpacks it where you choose, and **Send to › Zip file** bundles the selected files; **Send to** can also put a shortcut on the desktop
- Select several files at once with `Ctrl` on the desktop and in the explorer, and everything with `Ctrl+A`
- **Worksheets**: a worksheet can carry its own picture as the file's icon, new pages with a video or a triangle to play with, the teacher decides what each page says aloud, and the new-page dialog has an **All** tab with search and page previews
- The Control Panel's **Microphone** tab no longer cuts its texts, shows a coloured level bar, and records a short test you can play back
- The **PDF Viewer**'s pages pane looks like the Worksheet Editor's, and the **Save** button in **WordPad** and the **Worksheet Editor** is greyed out until something changed
