Actually, if I may, I think BBEdit 8 could use a more intuitive approach to the document drawer. If you have multiple windows open you simply have to hit command + ` to rotate between windows.
There needs to be a simple command like that to rotate between the documents in the drawer - a rotation that doesn't end, if you will, when the "next" document is the last document, then you need to switch to another keyboard command to go the other way. Not good, IMHO.
At least (for the money BBE costs), provide a slew of options for managing and switching documents.
Personally, I'd scrap the pull-down menu next to the right/left arrows to change docs (okay, not scrap, allow it, but allow it to be turned off) and I'd opt for a tabbed interface similar to the tabbing in Camino (or for Windows users, the tabbed interface in EditPlus).
BBEdit has unnecessarily given us an inordinate amount of keyboad commands and mouse movements to do something that should be much simpler.
I should be able to see all the doc open (tab them) across the top w/o the drawer open. The active document should be obviously highlighted in aqua. I should then be able to use a command + (some button) to jump between open tabs.
I use iKey (and AppleScript) to streamline my workflow, and I've had very little success trying to make an AppleScript to jump between open documents in a drawer. I've got a working model but only for two files I use all the time. Other docs I have to manually go to.
Just my .02.
