this pls. im thinkin of switching from vsc but intellisense and codelens are amazing. being able to chase down the origin of a function from a reference and find the references from the origin in a little subwindow is super handy
While this isn't Intellisense, Ryan Fleury made a code peek tool that is a step in this direction. Check out his extensions, they're really really cool. Especially power code mode and plotting :)
