When uploading a bulky folder with multiple sub-folders, the uploading order algorithm seems to be a bit random at times and often hard to follow. Most of the time after scanning all the files, it creates all the folders in the tree and then seems to upload the files in layer 1 then layer 2 etc (folder 1.1, 2.1, 3.1 then 1.2, 2.2, 3.2). However, this is not always in order (eg 5, 4, 2, 1, 3; and often chops and changes between folders by doing half of 1 then all of 2 then back to the other half of 1). The sub-folder layer issue makes it difficult to keep track of what has finished and what is pending.
It would be much better to be able to make it upload methodically the whole folder in its entirety with all of its files, sub-folder/layers and then move onto the next folder in the highest layer. (1.1, 1.2, 1.3 then 2.1, 2.2, 2.3 etc)
