It would be nice if the file (folder) transfer could be multithreaded. This would bring a speed improvement in cases where one transfers a folder that has a huge number of small files but in total not that huge (storage space wise). An example is when one transfers a 20GB file, it is much faster than a folder that allocates 20GB but has 30.000 files. It is understandable that just multithreading everything does not solve everything, but I think that in such situations a multithreaded solution could improve speed and performance. When searching for multithreading, I found 252019 (https://bugs.kde.org/show_bug.cgi?id=252019) and 252025 (https://bugs.kde.org/show_bug.cgi?id=252025), but they both do not talk about this use case.
