It would be very useful to have a structural outline of the currently opened TypeScript file in VScode.

For an example of what I mean, check out this screenshot of an outline from a Java file in Eclipse:

It displays the names of all types on top-level, and folded within them are the names of all fields and methods, including their names as well as parameter and return types. Clicking on a member in the outline jumps to the declaration. The icons indicate if the method is public (green) or protected (yellow).

As somebody who used Eclipse extensively in the past, I find it very difficult to program without such a view.
