Total Commander

I use sometime in place renaming Shift-F6 for moving file in sub folder in same directory. If i only have one file, i do not have the dialog and i miss folder name auto-completion.

Could it be possible to have an option that show in this case the same dialog with file name populated ?

You may simply write relative path into regular F6 dialog, and TC will move your file, and auto-completion will work. Just press F6 and start typing subfolder's name over selection (it will be erased).
