One thing that is missing (at least in the Linux version) is a shortcut to toggle the side bar. The Mac version used to use "ctrl+s", but that's what I associate with saving a file. I added a shortcut for "ctrl+b"; "b" for "bar" :
{ "keys": ["ctrl+b"], "command": "toggle_side_bar" }
To add this choose Preferences -> Key Bindings User
Be sure to add a comma to the line above as well.
