Feature Request: Freeze/Restart/Log Viewer Option for Users.
### Description
I've noticed a couple of things that could make using the dataset-viewer better. Here are three simple suggestions based on what I've experienced:

### Suggestions
1. **Keeping Parquet Viewer Steady**
    - Issue: Every time I tweak something like the content in the README, the Parquet viewer resets and tries to rebuild it.
    - Solution Idea: Add a "freeze" button for users so it stays where it is.

2. **Easier Viewer Restart**
    - Issue: It's definitely annoying to have to restart the viewer manually all the time for the dataset-viewer maintainers.
    - Solution Idea: Create a "restart" button for users so they can quickly reset the viewer.

3. **Log**
    - Issue: Just having access to the log of dataset-viewer errors would be very helpful. But the current log report is too abstract!
    - Solution Idea: Improve the error log report for better understanding.

Thanks for considering these suggestions!
