**Initial proposal to change the icon.** by** @jenkm
In most cases, the appearance of a file saving warning/question is expected by the user,
so it is more of a confirmation question than a warning about something unexpected.
The "Warning" icon is more suitable for cases such as a Python scripts security alert
when opening a file. Which is unexpected and requires special attention.
Overuse of the caution symbol in an alert diminishes its significance.
The Caution symbol is often used when errors occur (such as something not loaded
or lost connection), but saving a file is not the case.
The explanatory text also does not contain any warning, here is just a question.
Suggestion:
{F8941733, width=570}
Current:
{F8728700, width=570}
Example of a suitable use of a warning sign:
{F8381434, width=570}
