Prompt (pop-up window) before closing chart that has objects on it

Sometimes, you may close a chart by accident. This may happen if:

1) you click inadvertently with your mouse wheel in the chart tab

2) you have many charts open and you click in the wrong place while switching from one to the other

If the chart closes, you may lose hours of analysis. 

This could be easily solved with a prompt (a pop-up window) that asks you for confirmation before closing a chart that has objects in it (like trendlines, etc). 

This has been a recurring topic in the forum:
