I just installed this plug-in; it works great to an extent. I have some long posts and some really short ones (for various reasons). By default, this plug-in always adds the Read More text at the end of every post excerpt, even if trimming wasn't needed. I would like it to only display the Read More if the full post text doesn't fit in the post excerpt (in which case the post was never trimmed/limited). Is this possible?
