Nah it opens in a web browser window. I asked Otoy in the meantime and got this answer :
''If you want to load files in, you'll need to write an integration with our API (see http://docs.x.io/v1/docs/file-providers
If you're looking for a more complete solution, OTOY will be releasing something for users early next year, but I don't have any details on that right now.''
The silence around octane cloud is killing me! Release details already!!! LOL
