I noticed a couple of small things in the UI:
- The Files tab in the console should have a button to upload files in addition to drag&drop, because a button is more accessible and more discoverable. Failing that, a visual indication that you can drag&drop files would help somewhat.
- In the Share / Export dialog, the Export button should be visible from the start, just greyed out while the launch mode is set to IDE (default).
Good work otherwise! I like new improvements like the resizable panes, they help.
