I'd like to see the ability to download all of a profile's extensions because I tend to edit/create JS snippets outside of the web app. I also have had to copy extensions into other profile's and until there's a better way to do that I'm switching between profiles and copying/pasting.
Sam, we need a bulk copy feature and an improved code editor. The bulk copy is being built as we speak. Expect to see this introduced a little at time (for example, most likely user management will get this ability first.)
I also saw your comment earlier on github. I think it would be pretty cool to have Tealium do some github integrations. We'll get there. And we appreciate power users helping us move the product forward.
