When the user selects a plugin to upload, the UI does not show what they have chosen or indicate that it is ready for upload. Expected behaviour ought to be that the plugin filename is shown, and the Upload button should switch from disabled to enabled (with a visual indicator, too) - so that the user knows they can now upload the chosen plugin.
