It would be nice to notify the user if there are un-resolved conflicts in the merged file before winmerge closed

Hi, this is a feature request. Mainly from this discussion:

What is the correct way to config winmerge as merge tool under Windows, and using git-for-windows · WinMerge/winmerge · Discussion #1853

The notification is useful when we are in the git mergetool stage, but there are some un-resolved conflicts remaining before we close the winmerge.
