The new renaming process

I can't find anywhere else to gripe to adobe so I'm posting here. I do not like the new file renaming process. I used to be able to zoom in on the document and read a serial number while typing can't do that now. Also if I type a duplicate file name I can't modify it. I literally have to type it All. Over. Again. It's a real pain for what I use it for. Worked MUCH better before.
