Whenever I edit a file name in Lightroom Classic Library view, I want to be able to double-click and drag to select one or more words to edit in the file name, without changing the file extension. This is how the Mac Finder works. In Lightroom, I have to tediously drag the cursor (in a tiny font) back and forth to select exactly the end of the last word without selecting ".tif" or ".dng" or whatever. A period should be a word break character in the text box.
