Alphabet navigation on ipad disappeared

You recently removed the actual alphabetical letters (A-Z) from the file view. This has been a very useful feature to me. I use Dropbox on my iPad as a working live musician: All my song sheets are in a folder and I'd been able to jump to a particular letter quickly; for example looking for a song whose title starts with the letter "T," I could quickly tap on the "T" section then scroll to the actual song in another split second. Now you've replaced this with a tiny (tiny, tiny!) scrolling wheel, which is very difficult to use, especially in a live setting where time is of the essence. Please bring back the letters, thank you!
