Please provide the ability to connect to multiple SharePoint sites via O365, external delegation is used quite often.
As stated, I use external delegation quite often for most of my clients. This gives my company the ability to administer and record information directly to each clients SharePoint site via a dedicated library.
Please add a feature so that external delegated sites show up.

External Users should be able to use SharePoint App to access any tenant they have access to.
