Managing your site doesn't need to be a cumbersome process of switching between your browser and an ftp program to upload files.  With Seedling, file management can be done in your browser, while logged into your website.

We've included a great alternative to using an ftp client. 'eXtplorer' is a wonderful extension which opens a fully-featured file browser directly from the admin interface of your site.

eXtplorer has a desktop-application-like interface which lets you drag'n'drop files to your server with a full directory tree (this extension makes heavy use of the ExtJS Javascript Library.) You can use it to access and modify the files and directories on your server via FTP or direct file access.
