I'm using Beta (and Developer) on *nix, so don't know if this is an issue with Release or is an issue with other platforms...
There are available shortcuts for switching to tabs 1 through 9 as well as previous/next tabs. With any other browser I've used which allows keyboard tab switching there is a shortcut for switching to the last tab, usually it's "Alt+9". I realize I could do "Alt+1,Ctrl+PgUp", but that's not very convenient.
So, the short of it is, can there be an option to set a shortcut for "Switch to Last Tab"?
