> Was hoping there was an environment variable to get a list of the open tabs in a project. Is this possible?
You can look at the environment variables by enabling the Bundle Development bundle. Go into the Bundle Editor, and click on Filter near the bottom. Check the box next to Bundle Development. Now go to a document and press shift+ctrl+command+p. That should pop up a tooltip with all of the environment variables. Someone please correct me if I am mistaken and that is not all of the environment variables.
There is also this thing called TMTOOLS which supposedly hacks in a some extra functionality...but rather than go that route you might just bide your time and see if a future update possibly provides the features you are looking for.
