Selection of files within the web browser

Until recently, once the UI has changed, I could do an old-fashioned highlight of a file and then continue to highlight files for either download or deletion.  You could also select the first file in a folder and the hold shift-select the last file to select all files within that folder for ease of deletion.  NOW, we ONLY have the option to select a checkbox on the right edge of the file box area and check them one line at a time, then click the trash button to delete files.  This is SOOOOOO backward and annoying to have to do this when simply selecting a line or groups of lines for easy deletion was far better.  I have clients always reaching out asking how to select multiple files.
