For any text files attached to a note, I suggest to show the first few lines of that text file inside (inline) this note - at least in the wysiwyg editor. Ideally this excerpt would follow the file name / link to the file with some indent, cursive writing or other formatting.
This feature should ideally be available on all platforms.
