File manager upload does not have any progress bar, so it is not understandable until the whole chrome tab finishes loading. Uploading huge files is a little bit difficult for this reason, directly to the file manager. I hope an upload progress bar to the FM , overall a solid experience.
Another issue, you can not zip all the files inside a directory from the file manager. But you can zip a individual folder or file.
