Well, I sort of feel silly. I use digiKam for cataloging and tagging 
image files, and it turns out that digiKam already does display 32-bit 
floating point tiffs and also displays openexr images, at least it does 
after doing some updating today, not sure about before.

The exr files display with thumbnails. To have a thumbnail displayed by 
digiKam for a 32f tiff, the tiff needs to be exported with a thumbnail, 
which I haven't been doing.

digiKam will also scan for and show Krita 2.9 KRA and GIMP 2.9 XCF 
files, but none of them have thumbnails to show what might be in the 
layer stack.

Does the gnome file manager show thumbnails for GIMP 2.9 XCF files?

One reason why it has taken me awhile to sort through this "how to keep 
track of XCF files" is that digiKam kept crashing as I tried to scan in 
folders containing XCF files.

By moving folders with files that crashed digiKam, I was able to 
identify that the problem XCF files were all saved to disk back in 2013, 
which not coincidentally is the last time that I tried to scan XCF files 
using digiKam.

Resaving the problem XCF files using GIMP 2.9 from today, they don't 
crash digiKam. So whatever the problem was, it isn't a problem any more.

Now if only digiKam could display thumbnails for XCF files, that would 
be wonderful.

Well, actually checking, digiKam can display thumbnails for GIMP 2.8 XCF 
files, but not for GIMP 2.9 XCF files.
