Show the file list in tree view

[FranklinYu]

This is a feature request. It would be appreciated if the file is shown like a tree in file system.

I suppose that you're not just asking for a visual, but also interaction (e.g. collapsing directories)?

The file list is intentionally minimal, and if it doesn't fit the left side is truncated. This allows the reader to focus on the code at the right. A tree view can be pretty and somewhat more usable, but it can also make the UI a bit more crowded and get in the way.

What issues are you experiencing with the current simple list, and what are you hoping to resolve with a tree view?
