Allow extensions to add additional views

[mattiascibien]

One great feature that could be added to VsCode is the possibility to add more "tabs" in the letf area like the Git and the Debug one.

This way one developer can add other things like Sql server browser, github issues and more

If somebody already has an idea to where to add these extension pointe I will be glad to help.

That would be really cool, but it sort of implies that extensions need to be able to provide custom UI :)

[mattiascibien]

@daviwil I guess that providing UI is not possibile at the moment?

[daviwil]

As far as I know it isn't possible yet

[egamma]

Yes, not possible at the moment. Please see this doc https://code.visualstudio.com/docs/extensions/our-approach it describes our extensibility approach.

That would be really useful to add custom panel. I'd like to port my Atom's Remote-FTP extension to vscode.
