两个小的功能建议

1、文件管理器，如果当前是连接的ssh，建议可以类似winscp模式提供左右文件夹，左边是远端，右边是本地，而且可以直接相互拖拽上传下载
2、建议提供一个内置的文本编辑器，而且修改了之后可以直接上传，这个也是winscp比较好用的功能

The issue names no files, tests, or entry points, so begin by locating the SSH file manager and the text-editing/upload flows in the project. Clarify the scope of the two separate suggestions; done would mean a two-pane local/remote manager with drag-and-drop transfers and an editor whose changes can be uploaded.
