Hey there, I think it would be better for users to see the upload speed and remaining time for upload. And also we can have a transfer on hold, like when the internet stops and you have 5/10 files up you can resume later for the 5 others, this can be useful also for a work in progress situation when each time you have a file ready you upload, to condense content.
this could lay the floor for editable transfers as for now you can't edit a sent transfers which is kid of a must have feature. if a client ask to edit 1 file you cant.
