"Open folder..." feature?

Navigation with this extension is really awesome!

However, wouldn't it be even cooler if there was a possibility to implement the "Open folder..." feature?

For me, opening folders is much more frequent than opening single files (with the latter being done only if they're outside the currently opened project). Of course, there's the "Open recent..." command, but it often happens that I want to examine something fast by cloning it and immediately opening it in VSCode.

What do you think?

The issue names no files, tests, or entry points. First clarify how “Open folder...” should behave in the extension, then inspect the existing navigation and file-opening flow; done means a user can select a folder and open it in VSCode as described.
