Autofill Dragging, Multi-Cell Highlights, Quick Search, and Guest Battles

Hello spreadsheet learners! We updated the interactive practice screen and friendly multiplayer duel rooms to make daily learning smoother and more enjoyable.

Whether you want to look up a quick lesson or play a friendly formula match with a colleague, here is what is new:

1. Drag Corner to Fill Rows and Columns

You can now drag the small square on the bottom corner of any cell to copy numbers, dates, or formulas down a list in seconds.

2. Highlight Multiple Cells Easily

Click and drag your mouse or hold Shift + Arrow keys to select a group of cells together. The formula box shows the active area (like A1:C10) clearly.

3. Instant Lesson Search

Easily find any exercise without endless scrolling. Type a keyword into the search bar at the top of the sidebar, and the lesson list filters right away.

4. Balanced Split-Screen View

When you close the sidebar, the page balances neatly with instructions on the left and the spreadsheet on the right, giving you plenty of room to work.

5. Quick Battle Rooms for Guests

Playing a match with a friend is quick and easy. Guests can create a room, pick a topic, and share a 6-letter room code without needing to create an account first.

6. Clean Header with Next Exercise Button

We cleaned up the top bar and added a clear Next Exercise button so you can move forward as soon as you finish a task.
