I'm not sure about running an ftp client full screen - just tried it for a sec, well, I think I might have a use for that, one day.
It's mainly Spaces that people run into issues with, which is pretty widely used. Don't dismiss the value of FullScreen.. many people find fullscreen very useful, including me

I'm also using that queue drawer. I don't mind if it's in a drawer or in some floating window but I do need to be able to view it while also seeing the normal ftp interface. Same goes for the transcript, which is now displayed via Console. I don't like the extra clutter of the Console.
The drawer will not return, but by popular demand the queue will be visible within the main browser window simultaneously in an update, as soon as I can.
The transcript view was very limited and caused many issues, including increased processor usage, and even occasional crashes inside the OS API used for text rendering which I could never get to the bottom of, even with help from Apple. On the other hand, Console.app is perfect for navigating and managing log files such as these, they can be viewed 'live' as they get updated. In the next update I've added an entry to the sidebar in Console.app so you can quickly access the Logs folder maintained by Yummy FTP transfers.
The buttons seem to have grown as well: I now need to enlarge the client a bit to be able to view the remote editor button, a button I use a lot. I just prefer to have my ftp client running in the smallest possible but usable window.
Yes, they are slightly wider. How small is your 'usable' window now? (screenshot would be good)
