I have the same workflow for switching between tabs, although on Mac the default keyboard shortcut for switching Terminal tabs (Cmd + Shift + '[' or ']') was a little too cumbersome. I swapped it out with (Cmd + '[') which by default will take you to the next Terminal, not tab. I move left to right more, so it made more sense for me.

Easy enough to change in system preferences, though. And with using Vim NERDtree, or some other directory plugin, it makes sitting at the top level directory of your project, with multiple projects in multiple tabs, pretty easy.

Are you on Mac? If so, have you done anything to make tab-switching easier/faster? I'm interested because I only recently set mine up this way, and am always open to more efficient methods.
