I have a feature request for "Synchronize directories" dialog. Please add there an option "ignore file extension" to compare files in two directories only by filename without extension.
Use case: I am working with some images, I need to open each *.jpg image in folder A, make some manual changes and save it as *.png in folder B. And so on for every file. With "ignore file extension" option it would be easy to compare files in both directories with "Synchronize directories" dialog and find every file that is already edited/converted or every file that is untouched yet.
Maybe this option can be useful in other scenarios too. And I believe it's not hard to implement: just one additional condition in comparison function

Thank you!
