1. When creating a new file, it currently redirects to the classic “new file” page. Instead, it should open an inline editor similar to GitHub’s implementation, keeping the left tree view visible. The same behavior should apply to Upload Files and Apply Patch actions.
2. There is no way to add a new file for the root directory in the tree view UI.

You can do so in the main repo page in the code tab, same as to how its done on Github. Since I'm not aware of a way to view the root directory except for in the main repo page on the code tab (same on Github). Or perhaps I'm not understanding what you mean.

• It seems there is a bug that the icon to show/hide tree view will always be hidden.

• And maybe the commit box should be move to up right corner like what github did after the tree view introduced to the editor page.
