Along with "insert your favorite launcher" (Butler, LaunchBar, Quicksilver)
this used to be the must install add on, but I don't feel that way anymore.
Its been too hard to upgrade/download of late
(along with the going to the correct site for the correct version
and remembering when/where you purchased it)
and it just doesn't feel as integrated as it once was.

Also to me it seems as though we have been getting the upgrade
once every two weeks and as soon as we have an upgrade to Leopard
Saft is broken again.

Have been living without Saft installed for the past few months and
honestly I don't miss it. I have been loading up Safari Stand
which does what I want it to, including the "open last session"
option.
