Smarky was our manager for Safari bookmarks.  Although we will continue to sell and update it for the forseeable future, Smarky is no longer recommended because, beginning with one of the Safari 11 releases, in Safari’s Bookmarks > Edit Bookmarks, there is a Sort By > contextual menu which will sort items.  This is certainly not as powerful and flexible as Smarky, but given that installing and maintaining Smarky is a bit of work, we feel that most users are better off using this this new function which is built into Safari.

If at some point we decide to stop updating Smarky, we shall offer users a free upgrade to Synkmark.
