I'm another person who has tried several clip managers, but none I've tried has come close to
ClipMate, which has been my favorite for more than (gasp) 15 years. Unfortunately, ClipMate's developer seems to have disappeared from the forum and, perhaps, from working on the software as well. So while I continue to use and value ClipMate, I'm now keeping my eyes open for an eventual replacement. I took advantage of the BitsduJour offer for Clipstory, but I haven't (yet) installed it. But belated thanks, erikts, for calling attention to the offer.
