This is not a sale to miss! For the weekend of March 29th and 30th, 2008 only Leap is on sale for 50% off its list price from MacZot (ends up being about $30), and since its price is the main downside for the software I strongly recommend you check it out.
Despite my first impressions, Leap is the most exciting file system tagging app on the market and provides a great way for new users to get into tags (since it uses current folder hierarchies to supplement your tags). I’ve posted a bit more of an in-depth look at the strengths of Leap in the MacZot comments if you need more convincing. Incidentally, Leap was also updated to version 1.0.4 yesterday, but the update didn’t add much (just a couple of bug fixes).
