It seems at the moment when restoring you can only select a whole folder or a single file.
Say for example you want to restore a load of files from a folder but not restore all of them because some are large and your internet connection is not that fast, you’d either need to restore one file at time over and over or you’d have to download the whole folder full of files. Multiple selections would also be useful when you want to restore a few files that are located in different folders.
So some check boxes next to files or just holding down ctrl for multiple file selections would be very useful.
