In previous versions, save-as brought up a dialogue where I could start typing or changing the file name right away. Now, I either need to actually click on the file name or press tab three times to get there.

As someone who uses keyboard commands for speed and efficiency, this is annoying. The older version was faster and better. If you could fix this, I'd appreciate it.

On the plus side, you've finally allowed us to use Command-N for a new folder and Command-O to open a file on start-up – which are system-wide Mac standard commands that were somehow dropped many versions ago. Better late than never.
