Quote:...I do not want to use the "Save Layers" option that was also present in earlier versions as that results in files that I cannot view or even delete....
That was when the thumbnail option is checked and the file exported to the desktop. AFAIK that is fixed in the latest Gimp version. I think the fix is open in Gimp and re-export with thumbnails off.
---------------
As for keeping the tiff options, no load or save defaults in the export dialogue as with png. You could ask for that as an added feature for future Gimp https://gitlab.gnome.org/GNOME/gimp/-/issues
Do you use better than 8 bit ?
You can use the old gimp 2.8 file-tiff-save.exe plugin. Placed in your user plugins folder it supercedes the installed plugin and has the simple interface, just the compression options. (but no 16 bit export)
