If you go to the Developers Site, upper right hand side of page, and click on that, you'll get a page that shows what other apps the developer has made for OSX and/or OSX9 that will take you to VersionTracker Software Pages for that particular item. if any. In most cases, you'll find some additional links for other programs, as many developers have more than one. Also, if you notice on the page that you clicked (page two) up in the middle to right side of page is a link to the developers website where you can more than likely get even more info ... I noticed by going to this link http://www.urbanape.com/categorylist_html?cat_id=3 that the previous version of Zope Editor only worked well in Mozilla. I don't know about this version, but before you blast them, you should do some reading.
