If I'm editing an existing file and do a Save As, MarkdownPad opens the dialog with a default directory, and the full path of the file is in the File Name field. It would be better to open to the directory that the file is in, with only the filename and no path in the File Name field. Pretty much every editor works that way.
A related convenience that some editors have: If I'm editing an existing file, then the File Open dialog should also open to the directory of that file. That way if I have a collection of related files in a directory (or in nearby directories) and I'm editing one of them, it's easy to get to the others.
Any chance MarkdownPad could do these too?
