We now support showing inline values while you are debugging. Set "debug.inlineValues": true, in your settings.json. Have a workspace that you can debug (for example our smoke test repository) and verify:

• inline values appear with the correct value on the end of each line where they make sense
• inline values show only until the currently debugged line

Now try debugging for node2 adapter by just changing the type to node2 in your launch.json. Verify:

• Scope location is respected - inline evaluations are only shown from the start of the current scope to the current line.

Feedback on the presentation and usefullnes of inline values is welcome.
