Progress bar and total size on download button
My suggestion would be the “Download zip” button should have a progress bar and a total space the file is going to use. Didn’t realize that the file was still downloading after I hit “save”, thought the archive corrupted when it didn’t allow me to open
Having better control/visibility of the download (and the zipping if we stop pre-zipping), and an idea of the file sized in question is certainly important UI.
