This is one example from before installing Tahoe, that still shows the issue.
It also happens with JPEGs as well, although it is taking PM minutes to sort by file type, so that I can find a JPEG to attach, even though it's only a folder of 500 files.
Why does it take PM minutes to sort by file type? I assume it is deep scanning each file's contents to determine the true file type.
Is there a way to sort by extension only, which could take a thousandth of one second, instead of deep scanning file types? That's all I need in this case. I always have wondered why PM has no feature to sort or filter by file extension.
