I've created a new lightning app in a Winter 15 developer edition org.
I can access it using a URL such as: https://.lightning.force.com//.app
Now I've closed the developer console I want to go back and edit the lightning app some more.
How do I open an existing lightning app in the developer console?
I can't see an option to open an existing lightning app under the open menu item.
Nor can I see an option to open a lightning component directly from the developer console. I did have success from
Build > Develop > Lightning Components BETA using the edit link to get into the developer console.
