I know this has come up previously. I typically like my tools on the right-side of the interface, and I can't stand floating frames. I'd love to be able to just dock the tools on the right-side of the screen. Currently all I can do is undock the tools and let them float.
I'm not looking for preset workspaces, but the ability to save my workspace (panel and tool locations, and which panels are open/closed). This allows flexibility for different usage, and allows one to revert back to their favorite default interface. I know Publisher saves the interface from the last use, but in case I had more panels open on the last project, it would be handy just to load my standard preset and close all those windows at once and put things back to where I like them.
