Overwrite verification jams the whole queue

[tsqrl]

When I have a long queue to upload and then one file with same name happens to exist already, a dialog will appear asking about action for existing file. Like in file explorers usually, these verifications are asked after the whole queue has processed. With FileZilla they are asked according to queue order. Therefore an unpleasant surprise waits if you have left your computer for hours expecting that all the uploaded files are uploaded. I know that I can choose default action but it depends on the situation.
